Among them, the data for 240U and 240,241,242Np were observed for the first time. It was found that the mass distributions for all the studied nuclides maintain a double-humped shape up to the highest measured energy in contrast to expectations of predominantly symmetric fission due to the washing out of nuclear shell effects. From a comparison with the dynamical calculation based on the fluctuation-dissipation model, this behavior of the mass distributions was unambiguously attributed to the effect of multichance fission.}, pages = {222501-1--222501-6}, title = {Role of multichance fission in the description of fission-fragment mass distributions at high energies}, volume = {119}, year = {2017} }
