Low- and medium-spin negative-parity bands in the ¹⁸⁷Os nucleus

NUCLEAR REACTIONS ¹⁸⁶W(α, 3n)¹⁸⁷Os, E=37 MeV; measured Eγ, Iγ, γγ-coin, γγ(θ)(ADO), γγ(linear polarization) using AFRODITE array of 11 Compton-suppressed HPGe clover detectors at the K=200 cyclotron facility of iThemba Labs. ¹⁸⁷Os; deduced high-spin levels, J, π, multipolarities, bands, alignment plots, experimental Routhians, Nilsson configurations; calculated total energy surfaces contours in (ϵ₂cos(γ+30°), ϵ₂sin(γ+30°)) plane using the cranked Nilsson-Strutinsky-Bogoliubov (CNSB) models. Bands interpreted within the cranked shell model (CSM) and CNSB formalism.
