| Popis: | Rate equations are employed to the kinetic description of lattice defects, created in lithium fluoride by ion irradiation. The F centers are assumed to be created in a mobile state (anion vacancies or excited F* centers), having a certain relaxation time to become stable at room temperature. Concentrations of the F centers and their aggregates are analyzed depending on the irradiation conditions and model parameters. Comparison of the swift ion and electron/gamma irradiations using the suggested model captures the prominent experimental results of a higher complex defect fraction, which created under irradiation with the heavier projectiles. |
