Structural formation and thermal relaxation of quench-condensed Kr films: effect on EPR spectrum of trapped hydrogen atoms
Hydrogen atoms were trapped in a quench condensed Kr matrix and investigated by EPR. Each hyperfine
 component is a superposition of broad and narrow line. The spectrum of narrow lines shows an axial anisotropy
 of the hyperfine structure constant. The extent of the anisotropy is fou...

| description | Hydrogen atoms were trapped in a quench condensed Kr matrix and investigated by EPR. Each hyperfine
component is a superposition of broad and narrow line. The spectrum of narrow lines shows an axial anisotropy
of the hyperfine structure constant. The extent of the anisotropy is found to depend on both the deposition
temperature, Tdep, and the temperature of the solid sample, Tsample. As Tdep increases, the broad lines diminish
while the anisotropy of the spectrum of narrow lines becomes less pronounced. The spectrum of
narrow lines originate from H atoms in well defined environments and is attributed to a superposition of two
spectra given by the atoms in substitutional fcc and hcp sites. The spectrum of broad lines is assumed to originate
from the atoms trapped in highly disordered regions in the lattice. These regions are found to start relaxing
at Tsample as low as 12 K.
