Evidence for enhanced neutron-proton correlations from the level structure of the N = Z + 1 nucleus ⁸⁷₄₃Tc₄₄

NUCLEAR REACTIONS ⁵⁴Fe(³⁶Ar, 2np)⁸⁷Tc, E=115 MeV; measured Eγ, Iγ, charged particles, (particle)g- and γγ-coin using AGATA array of 11 triple-cluster segmented HPGe detectors for γ rays and DIAMANT array of 60 CsI(Tl) scintillators for particles at the GANIL accelerator complex. ⁸⁷Tc; deduced high-spin levels, J, π, rotational band, kinematic moments of inertia, alignment. Comparison with the structures of neighboring odd-mass N=44 and N=43 isotonic chains, and with shell-model calculations. Systematics of positive-parity yrast states in ⁸³Y, ⁸⁵Nb, ^87,89,91,93Tc.
