Description

We apply the generator coordinate method (GCM) in a fully microscopic calculation of the E2 decay lifetime of the isomeric states of 238U, 230Thand 232Th. The basis states have been generated by constrained HFBCS calculations with the potential SkM. Triaxial quadrupole deformations have been included. Comparison is made with experiment in the case of 238U and experimenters are urged to search for the predicted decays in the thorium isotopes. (orig.)
