Abstract

The differential ionization cross sections for charged hydrogenic targets with low Z at low to moderate energies were calculated using propagating exterior complex scaling (PECS) method. The PECS method with iterative coupling proved to be highly efficient, providing an estimated 100-fold reduction in total computation time compared with the PECS method using direct coupling. Scattering wave functions were calculated for the electron impact of hydrogenic targets with nuclear charge Z≤4. The results show that the angular distributions of the differential cross sections change systematically with increasing nuclear charge for energies above the peak total ionization cross section.
