Abstract：
The particle evaporation in the fission process of ¹⁰⁰Sn is studied using a diffusion model. It is shown that the shell influences strongly the proton emission whereas its effect on neutron emission is negligible, in contrast with the case of ¹³²Sn. It is due to the effect of the difference of neutron-to-proton ratio, N/Z,of the systems. This conclusion is further verified by comparing particle emission between ¹⁰⁰Sn and ¹⁰⁴Sn. Calculations indicate that high excitation energy weakens this N/Z effect.
