✦ Synopsis


Neutron deficient nuclei close to ~°°Sn have been studied using the NORDBALL Ge-detector array together with ancillary particle detectors. Evaporation residues from the compound nucleus taSTe were identified with charged particle and neutron detectors. In this paper a considerable extension of the level scheme of the nucleus t°2Cd is presented. The strongest cascade of the new level scheme reveals an irregular sequence of dipole transitions above I ~r = l0 + 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 states could successfully be interpreted as neutron particle and proton hole excitations with respect to the doubly closed core 1~Sn50. (~) 1997 Elsevier Science B.V.

Excited states of l°3Cd were studied in the reaction 58Ni(S°Cr,4pn)J°3Cd. The NORDBALL array with neutron and charged particle detectors was employed for the detection of y rays and light evaporated particles. The level scheme of l°3Cd was significantly extended.

Excited states of 56Co were studied in the reaction 27 A1(32 S,2p 1 n)56Co. The NORDBALL array with a Neutron Wall and a Silicon Ball was employed. The excited states were interpreted in terms of particle-hole excitations with respect to the doubly magic N = Z = 28 core.
