摘要：

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