Neutron- and proton-removal cross sections for nuclei around ^132Sn have been systematically measured. The measurements clearly show the effect of the N = 82 closed shells. Model calculations describing all processes leading to single nucleon removal residual nuclei provide a reasonable description of the neutron removal process but clearly overestimate the proton removal ones. This overestimation of the proton removal channels could be explained as due to the presence of short-range correlated neutron-proton pairs in nuclei.
