Abstract

AbstractA theoretical analysis of the hyperfine and superhyperfine interaction of copper and silver atoms stabilized in alkali‐halide crystals [1 to 4] is carried out. The hyperfine interaction is investigated on the basis of Adrian's theory [5] whose application to atoms stabilized in ionic crystals requires its further development. Particularly, the influence of the crystal field is taken into account. The results of theoretical calculations of hyperfine and superhyperfine interaction constants of copper and silver atoms in the lattices of alkali halide crystals are given. The overlap integrals for the wave functions of the unpaired electrons of copper and silver atoms and the wave functions of the nearest chlorine ions are calculated. The results of these theoretical calculations show a reasonable good agreement with the experimental data previously obtained [1 to 4].
