Selective interchannel coupling has been used in the present work as an effective computational strategy to idintify specific autoionization resonances and other correlation effects in the photoionization angular distribution asymmetry parameter for the case of valence ns subshell photoionization of atomic krypton and mercury. It is found that in the case of 6s photolonization of Hg, deviation of β from the non-relativistic value 2 in the energy region below the 5d ionization thresholds is a cumulative effect of the Cooper minimum in 6s photoionization and resonant excitations from the 5d subshells.
