Yrast structure of the shell model nucleus ⁸⁹Nb

NUCLEAR REACTIONS ⁶⁵Cu(²⁸Si, 2n2p), E=105 MeV; measured Eγ, Iγ, γγ-coin, γγ(θ)(ADO ratios), γ(linear polarization) using INGA array at 14UD TIFR-BARC Pelletron facility. ⁸⁹Nb; deduced high-spin levels, J, π, multipolarity, configurations, bands. Comparison with large-scale shell model calculations, and with systematics of level structures in N=48 isotones ⁸⁹Nb, ⁹¹Tc, ⁹³Rh, ⁹⁵Ag.

NUCLEAR STRUCTURE ⁸⁹Nb; calculated levels, J, π, configurations, partitions of wave functions. Large-scale shell model calculations using JUN45 and jj44b interactions.
