New experimental results on light-particle-accompanied neutron-induced fission of 236U are presented. The widths of the α-particle angular distributions are the same for 236U (nth) and 252Cf(s.f). This angular width appears to be a decreasing function of the total fission fragment kinetic energy. These results suggest that the characteristics of this mode of fission are not inconsistent with a semi-equilibrium model for scission.
