In-beam γ-ray spectroscopy of the neutron deficient 100Ag

  • Published:
Zeitschrift für Physik A Hadrons and nuclei

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 in-beam spectroscopy. The reactions 46Ti(58Ni,3pn) at 231 MeV and 64Zn(40Ca,3pn) at 167 MeV of the respective 58Ni and 40 Ca beams were used, and states up to 8.7 MeV excitation energy and spin I-20 were found in two main γ-ray cascades forming band-like structures of even and odd parity. Large scale shell model calculations suggest predominant πg −39/2 ν(d5/2,g7/2)3 and πg −39/2 ν(d5/2,g7/2)2h11/2 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 odd-parity levels.
