Abstract:
Neutron-deficient nuclei in the mass region A≈ 90-100 exhibit a large variety of phenomena. In this region the heaviest N = Z nuclei are identified and enhanced neutron-proton correlations are expected when protons and neutrons occupy identical orbitals. A variety of nuclear shapes are predicted and observed for A? 91, including superdeformed shapes. The nucleus 100Sn is the heaviest N = Z doubly magic nucleus believed to be bound. Knowledge of the shell structure around 100Sn is of utmost importance for understanding the nuclear shell model. New results on both the N = Z nucleus 88Ru, superdeformed structures in A≈ 90 nuclei as well as the first result on the level structure in 103Sn, and an extended level structure in 102In are presented. The limitations of using stable beams and targets and the possibilities with new radioactive beams are briefly outlined.
