Abstract
Fission-fragment mass distribution has been studied for the systems over an energy range of and , respectively, in a laboratory frame. The variance of the mass distribution for the system varies linearly with center of mass energy, while a significant anomalous behavior is found for the system . Coupled with our earlier observation for the system [T. K. Ghosh et al., Phys. Rev. C 69, 031603(R) (2004)], we propose that the accurate measurement of mass distribution is a powerful tool to look for the onset of a nonstatistical reaction mechanism in heavy-ion-induced fission of deformed heavy nuclei.
