Nuclear structure of ⁷⁶Ni from the (p, 2p) reaction

NUCLEAR REACTIONS ¹H(⁷⁷Cu, 2p), (⁷⁷Cu, X)⁷⁶Ni/⁷⁷Cu/⁷⁸Cu/⁷⁹Cu/⁷⁹Zn/⁸⁰Zn/⁸¹Ga, E=229 MeV/nucleon, [secondary ⁷⁷Cu beam from ⁹Be(²³⁸U, X), E=345 MeV/nucleon primary reaction]; measured yields of reaction products, Eγ, Iγ, γγ- and (recoils)p-coin using DALI2 array of NaI(Tl) detectors for γ detection, and ZeroDegree spectrometer for recoil identification, and MINOS device consisting of a liquid hydrogen target surrounded by a cylindrical time-projection chamber (TPC) at RIKEN-RIBF. ⁷⁶Ni; deduced levels, J, π, cross sections to excited states in ⁷⁶Ni, large Z=28 shell gap for nickel isotopes. Comparison with shell model calculations.

NUCLEAR STRUCTURE ⁷⁶Ni; calculated levels, J, π, spectroscopic factors, (p, 2p) exclusive cross sections using shell model and distorted-wave impulse approximation DWIA. Comparison with experimental data.
