Abstract

We have measured the energy spectra for the emission of long-range α particles from the spontaneous fission of Cf250, Fm256, and Fm257, and for tritons and protons from the spontaneous fission of Cf250 and Fm256. We have determined α, triton, and proton emission probabilities and estimated total light-particle emission probabilities for these nuclides. We compare these and known emission probabilities for five other spontaneously fissioning nuclides with the deformation energy available at scission and show that there is a possible correlation that is consistent with a one-body dissipation mechanism for transferring release energy to particle clusters.
