Partial photoionization cross sections of Kr 3d, 4s, and 4plevels in the photon energy range 37–160 eV

The relative photoionization cross sections of Kr 3d, 4s, and 4p levels have been determined from photoelectron measurements using synchrotron radiation in the photon energy range 37--160 eV. By using the total absorption cross sections from absorption measurements (Marr and West) the absolute partial cross sections have also been determined. The experimental results are compared with the theoretical calculations of Huang et al.
