Abstract [en]

Neutron-deficient nuclei in the mass region A approximate to 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 less than or equal to 91, including superdeformed shapes. The nucleus Sn-100 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 Ru-88, superdeformed structures in A approximate to 90 nuclei as well as the first result on the level structure in Sn-103, and an extended level structure in In-102 are presented. The limitations of using stable beams and targets and the possibilities with new radioactive beams are briefly outlined.
