Abstract: | The shape of the light absorption band by a local tetragonal center at the transition 1 5(x, y) is investigated in a semiclassical approximation. In addition to interaction with fully-symmetric (1), Jahn-Teller (3, 4) vibrations, inter-action is also taken into account with vibrations 5, which admix an electron level 4(z) to the electronic state 5, which is separated from 5 by the energetic gap . An analytic computation of the band shape is performed in the first order of the expansion of the form function in –1. An asymmetric two-hump band is obtained, where the long-wave maximum always has higher intensity than the shortwave maximum.Translated from Izvestiya Vysshikh Uchebnykh Zavedenii, Fizika, No. 12, pp. 62–67, December, 1987. |
