Transmission and photoconductivity of pure Te are recorded as a function of a magnetic field up to 6 T for several radiation energies in the submillimetre range under the pressure up to 3.4 × 10 8 Pa. The pressure dependence of the transverse hole effective mass is obtained from observation of cyclotron resonance (CR). Three groups of impurity lines are found with different behaviour under pressure. The pressure dependence of the energy and envelope function of the ground H‐like state in Te is calculated by a variational procedure within the effective mass approximation. The comparison with experiment makes it possible to evaluate the pressure dependence of the static dielectric constant.
