Abstract
The NORDBALL detector array has been used in a gamma-ray spectroscopic study of neutron deficient nuclei close to 100Sn. A beam of 270 MeV 5 8Ni ions was used to bombard a target of Fe-54. Reaction channel separ ation was achieved with a 4pi charged particle Si-ball together with a 1pi neutron detector wall. Altogether 29 final nuclei were identified and excited states were observed for the first time in 8 of them. The weakest identified channel was 100Cd which represented 4.10(-3) % of the observed total yield. Level schemes Of 102In, 104In and 108Sb cons tructed from gamma-gamma-particle-coincidence and gamma-gamma-angular correlation analyses are presented. The observed structures are discus sed in the framework of the nuclear shell-model. In 108Sb also a defor med, strongly coupled, level sequence is observed. This deformed struc ture is interpreted as built on a pig9/2(-1)xnuh11/2 configuration in agreement with TRS calculations.
