Abstract
The neutron deficient nucleus 100Ag three proton holes below and three neutron particles above the N=Z=50 shell closure at 100Sn has been identified and studied by inbeam spectroscopy The reactions 46Ti58Ni3pn at 231 MeV and 64Zn40Ca3pn at 167 MeV of the respective 58Ni and 40 Ca beams were used and states up to 87 MeV excitation energy and spin I20 were found in two main γray cascades forming bandlike structures of even and odd parity Large scale shell model calculations suggest predominant πg 9/2 −3 νd5/2g7/23 and πg 9/2 −3 νd5/2g7/22h11/2 structures with maximum spins Iπ=19+ and Iπ=22− respectively for the two level sequences The influence of πp1/2 vs νh11/2 excitations is discussed for low lying oddparity levels
