Simultaneous measurement of β-delayed proton and γ emission of ²⁶P for the ²⁵Al(p, γ)²⁶Si reaction rate

RADIOACTIVITY ²⁶P(β⁺), (β⁺p)[from ⁹Be(³²S, X), E=806 MeV/nucleon, followed by in-flight separation by the RIBLL1 fragment separator at HIRFL-Lanzhou]; measured E(p), I(p), Eγ, Iγ, βp- and βγ-coin, half-life of the decay of ²⁶P from correlated events of ²⁶P implants and successive decays using three double-sided silicon strip detectors (DSSDs), five Clover-type HPGe detectors, and five quadrant silicon detectors (Q SDs). ²⁶Si; deduced levels, J, π, Γ_p and Γ_γ of 5929, 3+ state. Comparison with previous experimental data, and with shell-model calculations.

NUCLEAR REACTIONS ⁹Be(³²S, X)²²Na/²³Mg/²⁴Al/²⁵Si/²⁶P, E=806 MeV/nucleon; measured reaction products and TOF-ΔE spectrum using in-flight separation by the RIBLL1 fragment separator at HIRFL-Lanzhou. ²⁵Al(p, γ)²⁶Si, T=0.03-1.1 GK; deduced energies and strengths of resonances, corresponding astrophysical reaction rates, and compared with data in JINA REACLIB database.
