Reinvestigation of the level structures of the N=49 isotones ⁸⁹Zr and ⁹¹Mo

NUCLEAR REACTIONS ⁸⁹Y(⁶Li, 4n2p)⁸⁹Zr, (⁶Li, 4n)⁹¹Mo, E=34 MeV; measured Eγ, Iγ, γγ-coin, γγ(θ)(ADO), (particle)γ-coin using GALILEO array with 25 BGO-Compton-suppressed HPGe detectors for γ rays, and EUCLIDES 4π Si-ball array for charged particles at the Tandem-XTU accelerator of INFN-LNL, Legnaro. ⁸⁹Zr, ⁹¹Mo; deduced high-spin levels, J, π, ADO ratios, multipolarities, configurations. ⁹¹Nb, ⁹²Mo; deduced ADO ratios for certain γ-transitions. Comparison with spherical-basis shell-model calculations.

NUCLEAR STRUCTURE ⁸⁹Zr, ⁹¹Mo; calculated levels, J, π, components of the wave functions and their partitions for spherical configurations for protons and neutrons. Comparison with experimental data. Systematics of energies in N=49 isotones: 9/2+, 13/2+, 17/2+, 21/2+, 23/2+ and 25/2+ states in ⁸⁹Zr, ⁹¹Mo, ⁹³Ru, ⁹⁵Pd, and those of 8+, 9+, 10+, 12+, 13+ and 14+ in ⁸⁸Y, ⁹⁰Nb, ⁹²Tc, ⁹⁴Rh.
