Data for the inclusive (n,px) reaction for 60 MeV neutrons on /sup 58,60,62,64/Ni are presented. Angular distributions for Q-value bins show a decrease of the forward peaking of the proton emission with increasing neutron excess. A marked dependence of the angle integrated spectra on (N-Z) is observed. The data are compared to hybrid and geometry dependent hybrid model calculations. Although these results predict the general shape of the spectra, they do not account for (N-Z) dependence. A neutron skin, as given by a hydrodynamic model, is added to the geometry dependent hybrid model, which predicts a higher precompound decay for high impact parameters. These results agree much better with the N-Z dependence of the data.
