Abstract
The influence of the interchannel interaction on the radiationless decay of the Xe 4d9np resonances is found to be extremely large due to the potential barrier effect. Interaction between the 5s5p-4dεf and 5p5p-4dεg decay channels reduces the decay transition amplitude associated with the outgoing g wave by a factor of about 3. The effect is confirmed by the good agreement between computed and measured photoionization cross sections and polarization parameters of the Xe 5p4mp levels.
