The method of Abakumov et al. who dealt with the evaluation of the lifetime of carriers in the field of Coulomb attractive centres in a strong electric field is applied here for a calculation of the field‐induced change of the capture coefficient of screened Coulomb centres. The use of a computer enables to study the field dependence in a broad interval of electric fields without restriction to weak or strong ones. The calculated values are compared with results of previous paper obtained by the method of Dussel and Boer. Results given by these two different approaches differ considerably in both the magnitude and the shape of functional dependence.
