摘要
Mass distributions of the fragments in the fission of Po-206 and the N = 126 neutron shell closed nucleus Po-210 have been measured. No significant deviation of mass distributions has been found between Po-206 and Po-210, indicating the absence of shell correction at the saddle point in both the nuclei, contrary to the reported angular anisotropy and prescission neutron multiplicity results. This result provides benchmark data to test the new fission dynamical models to study the effect of shell correction on the potential energy surface at saddle point.
