Neutron-deficient nuclei in the mass region -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 , including superdeformed shapes. The nucleus is the heaviest N=Z doubly magic nucleus believed to be bound. Knowledge of the shell structure around is of utmost importance for understanding the nuclear shell model. New results on both the N=Z nucleus , superdeformed structures in nuclei as well as the first result on the level structure in , and an extended level structure in are presented. The limitations of using stable beams and targets and the possibilities with new radioactive beams are briefly outlined.
