Evidence for nuclear superfluidity in 236U isomeric- and prompt-fission modes
Description
Isomer fission in /sup 236m/U, t/sub 1/2/=125 nsec, from 235U(d,pf) was compared with prompt fission 235U(n/sub th/, f), in twin experiments. Fine structure in the total kinetic energy, average total kinetic energy as a function of mass, and mass yield were observed in isomer fission of /sup 236m/U. This observation is compatible with a superfluid descent from saddle to scission points. Two peaks in the total-kinetic-energy distribution from isomer fission are observed near fragment mass 132, and this is interpreted as due to the proton-pairing effect at Z=50
