Tensor force role in β decays analyzed within the Gogny-interaction shell model

NUCLEAR STRUCTURE ^{10,11,12,13,14,15}C; calculated levels, J, π, ground-state energies. ^{10,11,12,13,14,15}N; calculated ground-state energies. Shell-model calculations with the effective interaction derived from D1S Gogny interaction with and without the tensor force. ^15,17O; calculated spectra using the Single-particle energies (SPEs) and two-body matrix elements (TBMEs) from the D1S interaction. Comparison with theoretical calculations using WBP interaction, and with experimental data.

RADIOACTIVITY ^10,11C, ^12,13N(β⁺); ^14,15C(β^-); calculated β spectra, B(GT) using shell model within the p-sd space and the D1S Gogny interaction with different components of tensor force. Comparison with theoretical calculations using WBP interaction, and with experimental data. Relevance to anomalously long half-life of ¹⁴C decay, and role of tensor force, cross-shell mixing, and three-body forces in β decay.
