研究了形变效应对 1 0 6MeV/u84Kr+ 2 7Al反应中断前粒子发射的影响 .发现通过测量的裂变前粒子多重性提取的裂变延迟时间将因此从 2 0× 1 0 - 2 1s减少到 5× 1 0 - 2 1s,表明增强的断前粒子发射有一部分来自形变效应的贡献 . The effect of deformation on particle emission before the interruption of 1 6 MeV / u84Kr + 2 7 Al reaction was studied, and the fission delay time extracted by the measured multiplicity of pre-fission particles was found to decrease from 20 × 10 21 to 5 × 1 0 - 2 1s, indicating that the enhanced pre-anterior particle emission is partly due to the contribution of the deformation effect.
