摘要：
The results of the temperature dependence of the Raman spectrum of CdGa2Se4 in the temperature range of 8 divided by 300 K are presented. It is found that the half-width of the A(1) symmetry line connected with Se-breathing mode at 138, 9 cm(-1) varies with temperature from 3,09 cm(-1) to 5,3 cm(-1). It is established that the broadening of this line is connected with weak anharmonicity due to three-phonon decay.
