| Popis: | The ESR method was used to study the regularities of formation of silver atoms in gamma-irradiated aluminium silicate modified by yttrium and containing109Ag istope ions introduced by various techniques. The existence of two types of silver atoms and an Ag 2 1 complex stabilized an the surface of a gamma-irradiated carrier has been established. g-Factors and superfine structure constants of spectral lines of paramagnetic silver particles belonging to various types observed on the surface have been calculated. Quantitative correlations of paramagnetic silver particles and the nature of their kinetic dependences in a broad temperature range (from 77 to 353 K) are determined by the number of silver ions introduced into the carrier and by the mode of introduction, thermal and vacuum pretreatment of the samples, irradiation dose and the temperature of investigating the gamma-irradiated surface. |
