High-spin states in the semimagic nucleus ⁸⁹Y and neutron-core excitations in the N=50 isotones

NUCLEAR REACTIONS ⁸²Se(¹¹B, 4n), E=48, 52 MeV; measured Eγ, Iγ, γγ-coin, γ(θ)(ADO ratios) at HI-13 tandem accelerator of CIAE-Beijing. ⁸⁹Y; deduced high-spin levels, J, π, multipolarity, configurations. Comparison with large-basis shell-model calculations using OXBASH code, assuming ⁶⁶Ni as an inert core. Level energy and Jπ systematics of N=50 even-even and odd-A isotones: ⁸⁶Kr, ⁸⁸Sr, ⁹⁰Zr, ⁹²Mo, ⁸⁷Rb, ⁸⁹Y, ⁹¹Nb and ⁹³Tc.
