Shell structure of the neutron-rich isotopes ^{69, 71, 73}Co

NUCLEAR REACTIONS ¹H(⁷⁰Ni, 2p), E=252 MeV/nucleon; ¹H(⁷²Ni, 2p), E=241 MeV/nucleon; ¹H(⁷⁴Ni, 2p), E=234 MeV/nucleon, [secondary beams from ⁹Be(²³⁸U, X), E=345 MeV/nucleon]; measured reaction products, Eγ, Iγ, γγ-coin, inclusive and exclusive σ using the DALI2 NaI(Tl) detector array for γ detection, the MINOS time-projection-chamber for p detection, the BigRIPS separator for secondary beam identification, and ZeroDegree spectrometer for reaction product identification at RIBF-RIKEN. ^69,71,73Co; deduced levels, J, π, configurations, half-life estimates of three low energy transitions in ⁶⁹Co. Distorted-wave impulse approximation (DWIA) analysis for cross sections. Comparison with shell model calculations using the Lenzi-Nowacki-Poves-Sieja LNPS and PFSDG-U interactions, and with previous experimental data.
