“…Good agreement was obtained for the experimentally well studied l~ [52], 1~ [39,53] and l~ [54], where also the vhl 1/2 levels are known. Also, to test the influence of the residual interaction on the A-dependence of these single particle orbits two types of interaction, an empirical realistic (SUS) and a schematic (SDI) one (see Sect.…”

The neutron deficient nuclei 9SAg, ~~ with Tz = 2 and 1~ l~ (Tz = 5/2) were studied in-beam following the reaction of 250 MeV 58Ni + 5~ Neutron and charged particle (p, 7) gated 77-coincidence spectra were used to identify these nuclei, which are populated with yields between 0.05% and 2% of the total residue cross section, and to determine their level schemes. In a comprehensive shell model study various approaches for the residual interaction were used to describe these newly and several previously studied neutron deficient nuclei. As a result predictions for the neutron single particle energies for ~~176 are obtained and used to discuss the next generation of experiments.

“…The level scheme as shown in Fig. 3 was constructed in the sequence of decreasing intensity of y-rays and continues the trend seen in the systematics of the heavier even Sn isotopes [10,11]. Due to the low production rate the analysis of yy angular correlation data was not feasible.…”

The very neutron deficient nucleus 104Sn has been idehtified in in-beam spectroscopy using the reaction 5oCr(58Ni, 2p2n) and neutron and charged particle multiplicity filter detectors. Excited states up to I-~ 10 and Ex = 4 MeV were observed and the level scheme is discussed in the frame work of the spherical shell model. The spectroscopic approach to the extremely neutron deficient doubly magic 94 has made substantial progress recently. 97Ag [1] and lo0Cd [2] have been studied in-beam and 98Ag in the 13+/EC decay of 98Cd [3] . From these studies fairly good knowledge of the proton-proton.(nn) and proton-neutron (nv) residual interaction and single particle binding energies was obtained. Much less is known about the neutronneutron (vv) interaction in the light semimagic Sn isotopes. Due to the near-degeneracy of the vd5/2, and vg7/2 orbitals at Z=50 the N=56 subshell closure disappears [4,5] and therefore little is known on the vgT/2 2 and vg7/2 d5/2 interaction. The experimental. situation is complicated by the fact that the Sn isotopes with A<105 touch the proton drip line so that they cannot be populated by 13+/EC decay. In the present work we have searched for light Sn isotopes populated in the reaction 5oCr+58Ni at 245 and 250 MeV energy of the Ni beam from the tandemcyclotron combination VICKSI at the Hahn-MeitnerInstitute. The target was a 2.1 mg/cm2 foil of 50Cr enriched to >97 % on a 23 mg/cm2 Au backing. The yrays were detected in the 6 and 12 detector version of OSIRIS [6] with the detectors positioned at 90 ~ and 90 ~ --25 ~ respectively. Evaporation neutrons were measured in a 16 respective 7 segment close packed detector array made from hexagons and pentagons [7].

“…There are, however, almost no investigations of odd-odd nuclei in this mass region, except two recent studies of 1~176 [4,5]. The present work is part of an investigation of yrast lines in light nuclei near the closed shells Z--20, N =20, (34C1, 37C1, 4~ 42Ca) and Z=28, N=28 (SSFe, S6Fe) [6][7][8], Z=50 [9] and of the //+-decay of high spin isomers in neutron-deficient nuclei with masses A~100-110 [10]. Results are given of an investigation of high spin states in ~~ by the reaction 9~ 3n).…”
