Abstract：
Effect of deformation on prescission particle emission was studied. The fission delay time extracted from the measured prescission light charged particle multiplicity of fission of light system ¹¹¹In, produced in 10.6MeV/u ⁸⁴Kr+ ²⁷Al collision, is reduced to 5×10 ^－21s from 20×10 ^－21s, if including deformation effect, which indicates that part of the excess of prescission particle emission comes from the deformation effect contribution. The reason is that deformation of the system leads to a decrease of the barriers for proton and α particle emission even larger than the increase of their binding energies.
