Decay properties of N=82 to 84 cadmium r-process nuclides

A chemically selective laser ion source has been applied in a decay study of very neutron rich Cd isotopes at CERN/ISOLDE. For the classical N=82 r-process "waiting-point" isotope /sup 130/Cd, a more precise half-life of 162+or-7 ms and a beta -delayed neutron branch of P/sub n/=(3.5+or-1....

Sumario:A chemically selective laser ion source has been applied in a decay study of very neutron rich Cd isotopes at CERN/ISOLDE. For the classical N=82 r-process "waiting-point" isotope /sup 130/Cd, a more precise half-life of 162+or-7 ms and a beta -delayed neutron branch of P/sub n/=(3.5+or-1.0) % were determined. Quite surprising results were obtained for the new isotopes /sup 131/Cd and /sup 132/Cd, which indicate the occurrence of new nuclear-structure effects beyond N=82. (13 refs).
