| Abstract: | The ESR spectra of the 5s1 state of Cd+, induced with gamma-ray irradiation, were measured for polycrystalline CaO, β-Ca(PO3)2 and glassy Ca(PO3)2 matrices. It has been found out that one of the hyperfine absorptions due to the magnetic nuclei (111Cd and 113Cd) reflects very senstively the structural fluctuation around the center in terms of pronounced line broadening. Such a feature was explained reasonably well by introducing the distribution of the hyperfine coupling constant. It was emphasized that Cd2+, the precursor of Cd+, is a very suitable probe to study the local randomness around Ca2+ in solids. |
