Abstract

Level schemes of $_{48}^{99} {Cd}_{51}$ and $_{49}^{101} {In}_{52}$ nuclei have been extended to high spin. The breakup of the doubly magic $^{100} Sn$ core has been observed. Large-scale shell model calculations based on realistic nucleon-nucleon interactions are in good agreement with the experimental data. These results provide a reliable basis to predict nuclear structure properties in $^{100} Sn$ and its neighbors. For example, the size of the $N = 50$ shell gap and the energy of the first excited state in $^{101} Sn$ have been deduced.
