Experimental and shell-model study of excited states in ⁵⁵₂₆Fe₂₉ and related notes on ⁵⁵₂₉Cu₂₆

NUCLEAR REACTIONS ²⁸Si(³²S, n4p)⁵⁵Fe, E=125 MeV; measured Eγ, Iγ, (particle)γ-, γγ-coin, γγ(θ)(DCO) using the Gammasphere array for γ detection, 4π Microball system for charged particle detection, and the Neutron Shell array for neutron detection at ANL-ATLAS and LBNL cyclotron facilities. ⁵⁵Fe; deduced high-spin levels, J, π, multipolarities, dipole structure, configurations. Comparison with shell-model calculations.

NUCLEAR STRUCTURE ⁵⁵Fe, ⁵⁵Cu; calculated high-spin levels, J, π, level half-lives, B(E2), B(M1), γ-branching ratios, configurations, occupation numbers relative to ⁵⁶Ni. Shell-model calculations with KB3G and GXPF1A interactions, with isospin breaking terms, using ANTOINE code. Comparison with experimental data.
