Abstract

We present the results of precision mass measurements of neutron-rich cadmium isotopes. These nuclei approach the N = 82 closed neutron shell and are important to nuclear structure as they lie near doubly magic 132Sn on the chart of nuclides. Of particular note is the clear identification of the ground-state mass in 127Cd along with the isomeric state. We show that the ground state identified in a previous mass measurement which dominates the mass value in the Atomic Mass Evaluation is an isomeric state. In addition to 127/mCd, we present other cadmium masses measured (125/mCd and 126Cd) in a recent TITAN experiment at TRIUMF. Finally, we compare our measurements to new ab initio shell-model calculations and comment on the state of the field in the N = 82 region.
