In-beam gamma-ray spectroscopy of Cd-102

Research output: Contribution to journalArticle


Neutron deficient nuclei close to Sn-100 have been studied using the NORDBALL Ge-detector array together with ancillary particle detectors. Evaporation residues from the compound nucleus Te-108 were identified with charged particle and neutron detectors. In this paper a considerable extension of the level scheme of the nucleus Cd-102 is presented. The strongest cascade of the new level scheme reveals an irregular sequence of dipole transitions above I-pi = 10(+) extending up to spin 17. A strongly populated rather regular side band consisting of four quadrupole transitions ranging from spin 9 to spin 17 was also discovered. This band was tentatively assigned negative parity. Shell model calculations were performed and a very good agreement with the experimental results was found. The excited stares could successfully be interpreted as neutron particle and proton hole excitations with respect to the doubly closed core Sn-100(50)50. (C) 1997 Elsevier Science B.V.
