Abstract:
Information on the first excited states in the N = Z = 41 nucleus 82Nb
sheds light on the competition of isospin T = 0 and T = 1 states in the
A ~ 80 region. The measurement was performed at the GSI laboratory
using fragmentation of a 107Ag primary beam at 750 MeV/u on a 4 g/cm2
9Be target. The fragments were separated and identified unambiguously
in the FRagment Separator. Three excited states were observed and the
half-life estimate for the isomeric state was extracted. A tentative spin
assignment based on the isobaric analogue states systematics in the Tz = 1
nucleus 82Zr, and transition probabilities indicate T = 1 character of the
first two excited states, and T = 0 for the isomeric state.
