The shell effects on the particle evaporation prior to fission for three Pb isotopes,~204Pb,~208Pb, and ~212Pb,as well as three Sn isotopes, ~128Sn,~132n, and ~136Sn, are explored by a diffusion model. Calculations show that themagnitude of shell effects in the emission of particles changes with tbe neutron-to-proton ratio N/Z of tbese fissioningnuclei, and this change is affected significantly by the spin and excitation energy of the system. It is shown that highangular momentum enhances the dependence of shell effects on the N/Z while high excitation energy weakens sucb adependence.
