摘要：

A study of the relevant single-particle diagram reveals the presence of a unique neutron orbital [505 11 2] which for N ≈ 144-150 passes through the Fermi surface for the distortion shapes characteristic of the fission-shape-isomeric state. This orbital gives rise to a specialisation energy in excess of 4 MeV for the second barrier peak. This energy increment is in turn expected to be associated with an increase in the half-life of the normal" fission-shape-isomer by a factor of about 1015. Recent experimental findings of an 0.3 year isomer in 241Pu is explained in terms of the specialisation energy connected with this orbital. © 1969."
