Description

Fission fragment mass distributions (FFMDs) for actinide nuclides at low excitation energies were investigated using the dynamical model (3D Langevin) with the potential energy surface obtained by two center shell model. The FFMDs for several actinide nuclides (U, Np, Pu, Cm, Bk, Cf), taken at the JAEA tandem facility, are well reproduced only by adjusting the neck parameter. The systematics of the neck parameter was adopted to calculate the FFMDs of fermium isotopes. (author)
