Abstract: | Fission-fragment mass and kinetic energy distributions and their correlations have been measured for the spontaneous fission of 244Cm. About 3.54 × 105 fission events were collected. The global mass distribution shows shoulders at μH ≈ 134 and μH ≈ 143?144. The peak/valley ratio is 86. The dip ΔEK value at symmetry is 13.4 ± 1.5 MeV. In the yields for high-kinetic-energy selected events, the masses 139 and 144 dominate. The results of 244Cm are compared with the other isotopes of Cm and discussed in terms of the structures present in the potential energy surface of the fissioning system caused by the structures in the nascent fragments. |
