The angle-resolved Kr L2,3M4,5M4,5 Auger spectra induced by proton impact ionization were measured at 1, 2.6 and 3.6 MeV proton energies where high-resolution spectroscopy techniques have been applied. The Auger energies and relative line intensities are compared with different earlier experimental data as well as our numerical results which have been obtained within a multiconfigurational Dirac-Fock approach. The alignment parameter A20 of the singly ionized krypton atoms has been extracted from the experimentally accessible anisotropy parameter A2 applying a special method, using the theoretical values of the angular distribution parameter α2.
