摘要: The multiplicity and the energy of prompt neutrons from fragments for 233U(n th, f)were measured as functions fragment mass total kinetic energy. Average neutron against showed a nearly symmetric distribution about half division with two valleys at 98 145 U. This shape formed contrast saw-tooth average multiplicity. It indicates that shell-effects, which are pronounced having proton number or close to magic-number 50 82, affected emission process. slope depended on minimum 130 obtained data were applied determine excitation system, resulting value in typical asymmetric fission lied between 22 25 MeV. agreed determined by subtracting Q-valu...
