This was done in an fusion-evaporation experiment, using a 58 Ni beam on a 45 Sc target. Even-parity core excited states in these nuclei are very well reproduced in large scale (LSSM) calculations in which particle-hole excitations are allowed with up to five g 9/2 protons and neutrons across the N = Z = 50 gap, to the g 7/2 , d 5/2 , d 3/2 , and s 1/2 orbitals. The odd-parity states can only be qualitatively interpreted though, employing calculations in the full fpg shell model space, but with just one particle-hole core excitation allowed. A more complete model including odd-parity orbitals is need for the description of core excited states in the region of 100 Sn.
