Abstract
The neutron deficient nucleus100Ag, three proton holes below and three neutron particles above the N=Z=50 shell closure at100Sn, has been identified and studied by in-beam spectroscopy. The reactions46Ti(58Ni,3pn) at 231 MeV and64Zn(40Ca,3pn) at 167 MeV of the respective58Ni and40Ca beams were used, and states up to 8.7 MeV excitation energy and spin I⋍20 were found in two mainγ-ray cascades forming band-like structures of even and odd parity. Large scale shell model calculations suggest predominantπg 2/−39 ν(d5/2,g7/2)3 andπg 2/−39 ν(d5/2,g7/2)2h11/2 structures with maximum spins Iπ = 19+ and Iπ=22−, respectively, for the two level sequences. The influence ofπp1/2 vs.νh11/2 excitations is discussed for low lying odd-parity levels.
