Cranked relativistic Hartree-Bogoliubov theory: Superdeformation in the $A\sim 190$ mass region

Abstract

A systematic investigation of the yrast superdeformed (SD) rotational bands in even-even nuclei of the $A\sim 190$ mass region has been performed within the framework of the cranked relativistic Hartree-Bogoliubov theory. The particle-hole channel of this theory is treated fully relativistically, while a finite range two-body force of Gogny type is used in the particle-particle (pairing) channel. Using the well established parameter sets NL1 for the Lagrangian and D1S for the Gogny force, very good description of experimental data is obtained with no adjustable parameters.Comment: 5 pages, 2 Postscript figures, uses sprocl.sty, contribution to the Proceedings of the International Conference ``Bologna 2000, Structure of the Nucleus at the Dawn of the Century'
