Abstract
The energies of odd excited states of shallow acceptors in uniaxially compressed germanium have been calculated as functions of strain and oscillator strengths for transitions from the ground state of an impurity. The calculation allows both a detailed interpretation of the lines previously observed in the photoconductivity and absorption spectra of uniaxially compressed germanium and description of the evolution of these lines with increasing the strain. It has been shown that the photoconductivity of uniaxially compressed germanium depends on the polarization of incident electromagnetic radiation.
