Shell-model-based deformation analysis of light cadmium isotopes
AbstractLarge-scale shell-model calculations for the even-even cadmium isotopes Cd98–Cd108 have been performed with the antoine code in the π(2p1/2;1g9/2)ν(2d5/2;3s1/2;2d3/2;1g7/2;1h11/2) model space without further truncation. Known experimental energy levels and B(E2) values could be well reproduced. Taking these calculations as a starting ground we analyze the deformation parameters predicted for the Cd isotopes as a function of neutron number N and spin J using the methods of model independent invariants introduced by Kumar [Phys. Rev. Lett. 28, 249 (1972)PRLTAO0031-900710.1103/PhysRevLett.28.249] and Cline [Annu. Rev. Nucl. Part. Sci. 36, 683 (1986)ARPSDF0163-899810.1146/annurev.ns.36.120186.003343].
