In ion-atom collisions the pseudostate method has achieved great success for calculations of K-shell ionization cross sections. However, applications of this method are limited to the calculations for total ionization cross sections. In the present work, we have calculated the energy distributions of ejected electrons in ion-atom collisions by the use of pseudostates. Using the Slater-type orbital (STO) as a basis function, we expand the atomic wave functions in terms of STO's and diagonalize the atomic Hamiltonian with this base set. The electron transition probabilities to continuum states are given by those to discrete states with positive energy eigenvalues; i.e., the pseudostates. The calculations of the transition probabilities are made within the framework of the semiclassical approximation (SCA), assuming the straight-line trajectory. 6 refs., 1 fig.
