Research output › peer-review

Abstract

Dichroism is induced in potassium chloride crystals containing M-centres by irradiation at I ow temperatures with polarized light in the F-band. This dichroism arises from a reorientation of the M-centres by ionic motion. The population of the six possible orientations of the H-centre can be described by six relaxation modes, depending on the direction of polarization of the light. Using group theoretical considerations, the relaxation modes are derived for the cases where the polarization of the light is in the [001] and [011] directions.
