Ionization of hydrogen atoms by electron impact at 1eV, 0.5eV and 0.3eV above threshold
Abstract
We present here triple differential cross sections for ionization of hydrogen atoms by electron impact at 1eV, 0.5eV and 0.3eV energy above threshold, calculated in the hyperspherical partial wave theory. The results are in very good agreement with the available semiclassical results of Deb and Crothers DC02 for these energies. With this, we are able to demonstrate that the hyperspherical partial wave theory yields good cross sections from 30 eV DPC03 down to near threshold for equal energy sharing kinematics.
