Description

The influence of the quadrupole pairing interaction on the value of the collective potential and inertia of fissioning nuclei is presented. The calculation employed a Nilsson potential having quadrupole and hexadecapole deformations. The collective inertia and potential found were then used to estimate the spontaneous fission lifetimes of a number of Fm isotopes. It was found that the calculated lifetimes are very sensitive to the presence of the quadrupole pairing forces. (orig.)
