1. INTRODUCTION
The works of S. Rabin published during 1949–62 are
considered by the world scientist society to be first ap-
plication of accelerators for analysis of substances by
means of prompt radiation measurements.
In the Former Soviet Union utilization of the prompt
radiation of nuclear reactions for analytical aims was
firstly realized by E.V. Inopin, S.P. Tsytko (Ukraine In-
stitute of Physics and Technology, Kharkov) and
M.I. Guseva (Institute of Atomic Energy, Moscow) in
1959 [2]. These authors investigated the depth profile
and distribution nature of silicon atoms implanted into
copper and titanium. The resonances of 28Si(p,γ)29P re-
action were used to resolve this problem.
2. METHODS AND THEIR APPLICATION
Rutherford backscattering, nuclear reactions,
charged particle induced Х- rays, activation analysis are
systematically used at KIPT to solve science and tech-
nological problems in the field of metals and alloys [3-
16], semiconductors [18-31], magnetic materials
[32,33], radiation physics [21,23,24,28,33], physics of
metal oxide combinations including of high – T super-
conductors [34,35,36], analytical chemistry, environ-
ment objects analysis.
In prompt radiation analysis the presence of an ele-
ment is detected through the nuclear radiations emitted
instantaneously from nuclear reactions produced in the
target by the irradiating beam. One of the important ad-
vantages of prompt analysis and the backscattering tech-
niques is that they can be used to measure the depth dis-
tribution of elements in the surface or near-surface re-
gions of the sample. The dependence of the characteris-
tics of the emitted radiation on depth is due to the ener-
gy loss suffered by the incident ions as they penetrate
into the sample and also to the energy losses suffered by
charged particles emitted from the reaction as they
emerge from within the sample.
Since nuclear reaction analysis can provide essen-
tially background-free detection of light elements, depth
distributions of trace amounts within the near-surface
region can de measured. The primary emphasis in our
discussion of prompt radiation analysis is the determina-
tion of concentration depth profiles of trace element im-
purities. In the use of prompt analysis for depth profiles,
two different methods are applied, namely, the energy-
analysis method and the resonance method. The former
is used when the cross section of a nuclear reaction is a
smoothly varying function of energy. The latter method
is used when a sharp peak (resonance) in the cross sec-
tion as a function of energy is present, and the depth
profile is derived from a measurement of the nuclear re-
action yield as a function of the energy of the analyzing
beam.
Widespread application of accelerators and nuclear
physics methods is conditioned by possibility to deter-
mine kind, concentration and distribution of element mi-
cro quantities to research migration and diffusion mobil-
ity of these elements and their isotopes. Using orienta-
tion effects and channeling particles promotes:
− to find location of atoms implanted in to the lattice
or (in the case of complicated crystals) to determine
sublattice in which implanted ions are placed;
− to determine profile of distribution of implanted
atoms and radiation defects created by the implantation;
− to search composition, structure, orientation, pro-
duction and decay of simplest defects;
− to search mechanism and features of ion motion in
well-ordered surroundings etc.
To identify elements and isotopes we used Ruther-
ford backscattering and nuclear scattering of hydrogen
and helium ions, the ion induced X-rays as well as
prompt radiation of reactions are given in the following
table:

The data of basic investigations in the fields of nu-
clear spectroscopy and atomic nucleus structure are pre-
condition of these experiments.
3. METALS AND ALLOYS
During 1964-1970 the nuclear physics methods and
KIPT accelerators were applied for study of zirconium
oxidation and oxygen diffusion in zirconium, niobium
and their alloys. To solve the problems it was proposed
to use radiation of the resonance reactions (p,γ) [3,4]
and (p,α) [5,6,] which occur at the interaction of inci-
dent protons with 18O isotope nuclei. The coefficients
of oxygen diffusion in zirconium and niobium were de-
termined in the wide range of temperature [7,8]. The
mechanism of anion and cation transfer by oxidation
process in gas and steam of the water was studied.
For the first time in the Former Soviet Union (1969)
the method of composition matter analysis by proton
and α-particle induced X-ray radiation was proposed in
KIPT. This perspective technique which is widely used
in the world at present was successfully developed due
to working out and creation of semiconductor Si(Li)-de-
tectors for X-ray spectrometers.
Qualitative new stage in application of accelerators
and nuclear physics methods began since discovery of
aligned effects. KIPT team was one of the first scientific
groups which observed fundamental effect – redistribu-
tion of particle flux density in transverse plane of chan-
nel [9].
Using channeling protons and helium ions permited
to determine location of oxygen and deuterium atoms in
niobium [9,10], helium in tungsten [11], boron in tung-
sten [12], nitrogen in niobium and molybdenum [13,14],
carbon in rhenium and nickel [15], oxygen in tanta-
lum [16].
4. SEMICONDUCTORS
Localization of atoms of boron and phosphorus
which are widely used elements in microelectronics in-
strument production technology was determined in sili-
con by channeling particle method [17,18,21]. Besides
depth profiles of interstitial atoms and radiation damage
silicon atoms were found [20,22,23]. Thermal stability
of defects was fixed. Optimal conditions of base struc-
ture forming were determined.
The cycle of investigations of ion implanted 3A5B
binary compounds (indium antimonide, indium ar-
senide, indium phosphide, gallium arsenide) was carried
out analysing prompt radiation induced by channeling
particles [24]. Data concerning localization of atoms of
1-st and 2-nd periods of the element table in 3A5B were
obtained [25]. Modification of implanted atom localiza-
tion caused by irradiation and annealing was fixed [26].
The regularities of forming and annealing radiation de-
fects in implanted structures were studied. Depth pro-
files of implanted atoms and radiation defects were de-
termined. The contribution of sublattices in the radiation
defect production process was determined. The results
of these works served as a foundation for development
and optimization of basic structure technology of infra-
red (IR) detectors. It shown IR–detectors with optimum
parameters can be made on the base of beryllium –
doped indium antimonide [27,28].
5. METAL OXIDES AND MAGNETIC MATE-
RIALS
Combination of nuclear physics methods and
charged particle accelerators turned out the perspective
way of investigation of composition and properties of
oxidic metal compounds including high–Tc supercon-
ductor ones [30]. It was carried out the cycle of works
for the sake of optimization of making technology of
La2-xSrxCuO4 and Nd2-xCexCuO4 crystals [31]. The
crystal structure modification was investigated depend-
ing on furnace charge and agglomeration conditions. It
was shown oxide sublattice has larger radiation destruc-
tion rate in comparison with cation one. The diffusion
coefficients of oxygen to YBa2Cu3O7-y were deter-
mined [32].
Application nuclear physics methods and accelera-
tors for investigation of properties of ferrite oxide metal
compounds, which are used in magneto–optics, comput-
er engineering and quantum electronics is essentially
only started now. Tl4+ and Tl3+ ions in the corund
crystal lattice are shown to be placed in tetrahedral in-
terstitial space and interstitial space which is shifted
along the <0001> direction of the aluminum sublattice
[29]. There was found the localization of the boron and
nitrogen atoms in the ferrogarnet film lattice. The im-
planted alloy ion distribution and distribution of radia-
tion defects created by the ions were determined [33].
