The angular distribution parameter, ..beta.., has been measured for the resonant Auger spectra in Kr following 3d..-->..5p excitation. Unusually low values, close to -1, were seen for two bands. From optical spectroscopy data these bands are assigned to the final states 4p/sup 4/(/sup 3/P)5p(/sup 4/P/sub 5/2/, /sup 4/P/sub 3/2/, and /sup 4/D/sub 5/2/). According to angular momentum transfer theory, some of the transitions could be parity unfavored, yielding ..beta.. values of -1, but additional theory is required for a complete understanding. Implications for angular studies of highly resolved Auger spectra are discussed.
