Superheavy elements at high angular momenta
(1980) In Physics Letters B 92(3-4). p.223-228- Abstract
Potential-energy surfaces at high spin are calculated for nuclei in the superheavy region by use of the cranked Nilsson hamiltonian. It is found, that the maximum fission barrier is shifted from the doubly magic 298114 to nuclei with fewer protons and more neutrons, as the spin increases. We also estimate, by use of simple models, the half-lives associated with alpha-decay, gamma-decay and fission as functions of spin along the yrast line. As a representative example a detailed discussion of the yrast spectrum of 298114 is presented.
