Differential cross sections and angular-correlation parameters for the excitation of hydrogen atoms to<i>n</i>=3 and<i>n</i>=2 states by electron impact between 16 and 100 eV

Abstract

Differential cross sections and angular-correlation parameters relating to elastic scattering and electron-impact excitation of hydrogen atoms to the n=3 and n=2 states are presented for energies of 16, 20, 35, 54, and 100 eV. Results are obtained from a close-coupling calculation using a 17-state target basis including seven exact states and ten pseudostates. Comparisons are made with experiment and with other calculations.
