β-decay spectroscopy of ²⁷S

RADIOACTIVITY ²⁷S(EC), (β⁺), (β⁺p)[from ⁹Be(³²S, X), E=80.6 MeV/nucleon]; measured reaction products, Eγ, Iγ, Ep, Ip, pγ-coin, T_1/2 of ²⁷S decay using double-sided silicon strip detectors for particle identification, and HPGe detectors for γ detection at HIRFL, Lanzhou. ²⁷P; deduced levels, J, π, β⁺ and ϵ feedings, logft, B(GT), mass excess, Q value of ²⁷S decay. Comparison with shell model calculations using universal sd (USD) Hamiltonian, and with the structure of mirror nucleus ²⁷Na. Relevance to nuclear physics input for accurate modeling of nova and x-ray burst observables.

NUCLEAR REACTIONS ⁹Be(³²S, X)²²Na/²³Mg/²⁴Al/²⁵Si/²⁶P/²⁷S, E=80.6 MeV/nucleon; measured two-dimensional identification plot of ΔE versus TOF for the reaction products using RIBLL1 separator at HRIFL, Lanzhou facility. ²⁶Si(p, γ), E=0, 318, 762 keV; deduced resonance parameters, S factor at zero energy, and thermonuclear reaction rate. Comparison with experimental data, and literature values.
