Spectroscopy of atomic and molecular defects in solid ⁴He using optical, microwave, radio frequency, magnetic and electric fields (Review Article)
A little more than a decade ago our team extended the field of defect spectroscopy in
 cryocrystals to solid ⁴He matrices, in both their body-centered cubic (bcc) and hexagonally
 close-packed (hcp) configurations. In this review paper we survey our pioneering activities in the&#...

| description | A little more than a decade ago our team extended the field of defect spectroscopy in
cryocrystals to solid ⁴He matrices, in both their body-centered cubic (bcc) and hexagonally
close-packed (hcp) configurations. In this review paper we survey our pioneering activities in the
field and compare our results to those obtained in the related fields of doped superfluid helium and
doped helium nanodroplets, domains developed in parallel to our own efforts. We present experimental
details of the sample preparation and the different spectroscopic techniques. Experimental
results of purely optical spectroscopic studies in atoms, exciplexes, and dimers and their interpretation
in terms of the so-called bubble model will be discussed. A large part of the paper is devoted
to optically detected magnetic resonance, ODMR, processes in alkali atoms. The quantum nature
of the helium matrix and the highly isotropic shape of the local trapping sites in the bcc phase
make solid helium crystals ideal matrices for high resolution spin physics experiments. We have investigated
the matrix effects on both Zeeman and hyperfine magnetic resonance transitions and
used ODMR to measure the forbidden electric tensor polarizability in the ground state of cesium.
Several unexpected changes of the optical and spin properties during the bcc—hcp phase transition
can be explained in terms of small bubble deformations.

 Several unexpected changes of the optical and spin properties during the bcc—hcp phase transition
 can be explained in terms of small bubble deformations. The research work presented above is the fruit of
 more than a decade of experimental and theoretical
 efforts carried out by a number of undergraduate students,
 Ph. D. students, and postdocs, and with the invaluable
 support of mechanical and electronics technicians
 and engineers. All their individual contributions
 are acknowledged. The doctoral thesis works that
 have emerged from this line of research were presented
 by Markus Arndt [79] and Stephen Lang [80] at the
 Ludwig-Maximilians Universitt in Munich, by Taro
 Eichler [81] at the Friedrich-Wilhelms-Universitt in
 Bonn and more recently by Daniel Nettels [82],
 Reinhard M ller-Siebert [20] and Simone Ulzega [66]
 at the University of Fribourg. One of us (A.W.) acknowledges
 his colleague and friend Sergei Kanorsky
 who submitted the original EDM proposal to the
 Max-Planck-Institute for Quantum Optics and with
 whom he initiated the first heroic steps of this research.
 We thank Paul Knowles for his critical reading
 of the manuscript.
 The research was funded partly by the individual
 host institutions and by the national funding agencies
 in Germany (Deutsche Forschungsgemeinschaft,
 DFG) and in Switzerland (Swiss National Science
 Foundation, SNF). We particularly acknowledge the
