Abstract

The K-shell ionization cross sections by positron impact have been calculated for Cu in the binary-encounter approximation by the use of velocity distribution of the target electron from the nonrelativistic and relativistic hydrogenic models. The results are compared with the values obtained with velocity distribution in the free-fall model. The effect of choice of atomic models on the ionization cross sections is discussed. We found that the present results are in agreement with the experimental data and other theoretical values.
