Long-wave acoustic phonons assisted relaxation ratesof the lower excited states 1s(T), 2p0, 2s, 3p0, 2p±, 4p0,3p±of antimony donors in a germanium crystal are calculated.The influence of uniaxial stress in the crystallographic direction[111]on relaxation rates has been considered. The calculationresults have been compared with the measurement data ofrelaxation times of nonequilibrium donor states by the pump-probe method. A comparison is also made with the lifetimesobtained experimentally by the method of studying submillimeterphotoconductivity.
