Abstract
The present status of experimental approach to Sn-100 in the spectroscopy of excited states is landmarked by the T-z = 3/2 nuclei between (95)pd and In-101 and the T-z = 1 nuclei Pd-94 and Cd-98. The detection limits with Pre-EUROBALL gamma-arrays and ancillary detectors are below the 10(-5) level of the total fusion- evaporation residue cross section. A large scale shell model analysis of the existing data reveals the shell structure at Sn-100, which shows a remarkable similarity to Ni-56. Evidence for an increasing proton-neutron interaction in approaching the N = Z line is deduced from high spin isomers and spherical yrast lines. The effective E2 operator for protons and neutrons and implications for a low lying particle-hole (ph) E2... (More)
