The nondipole parameters that characterize the angular distribution of the photoelectrons from the 3d subshell of Cs are found to be altered significantly by the inclusion of correlation in the form of interchannel coupling between the 3d{sub 3/2} and 3d{sub 5/2} photoionization channels. A prominent characteristic maximum is predicted only in the parameters for 3d{sub 5/2} photoionization, while the effect for 3d{sub 3/2} is rather weak. The results are obtained within the framework of the generalized random-phase approximation with exchange (GRPAE), which in addition to the RPAE effects takes into account the rearrangement of all atomic electrons due to the creation of a 3d vacancy.
