β-delayed γ decay of ²⁶P: Possible evidence of a proton halo

RADIOACTIVITY ²⁶P, ²⁴Al(β⁺), (EC)[from ⁹Be(³⁶Ar, X), E=150 MeV/nucleon using A1900 fragment separator and the Radio-Frequency Fragment Separator (RFFS) at NSCL-MSU]; measured Eγ, Iγ, ²⁶P ions, Eβ, Iβ, γγ-, βγγ-coin using GeDSSD detector for ions and β particles and SeGA array for γ rays. ²⁶Si; deduced levels, J, π, Iβ feedings, B(GT) strengths, logft, mirror asymmetry, proton halo. Comparisons with β decay of ²⁶Na mirror nucleus, previous experimental data for ²⁶Si levels, and USDB shell-model calculations. ²⁴Mg; observed γ rays. ²⁵Al(p, γ)²⁶Si, T₉=0.01-0.5; calculated astrophysical reaction rates.
