摘要
In a joint experimental and theoretical effort, we carried out a detailed study of electron impact excitation of the 4p(5) 5s states of Kr. We present angle-differential cross sections over the entire angular range (0 degrees-180 degrees) for a number of energies in the near-threshold region, as well as energy scans for selected angles. The experimental results are in very satisfactory agreement with predictions from a fully relativistic Dirac B-spline R-matrix model.
