 note = {We measured the Kr photoelectron spectrum in the region close to the 3p ionization threshold. Our high- resolution measurements allowed a clear observation of new spectral structures due to electron correlation effects. Analysis based on relativistic multiconfiguration calculations could explain these new peaks as due to strong configuration interactions between the 3p-1 state and 3d-2nl states. Calculated and experimental data for peak assignments and intensity distributions are in good agreement. In addition, we measured the anisotropy parameter , which also agreed well with theory. These findings provide a detailed view of strong configuration interactions between the 3p-1 and 3d-2nl inner-shell hole-states.},
