Experimental study of the ²⁴Na^m(d, p)²⁵Na reaction and implications for the influence of the ²⁴Al^m isomer on rp-process nucleosynthesis

NUCLEAR REACTIONS ²H(²⁴Na, p)²⁵Na, E=85.5 MeV, [secondary ^24mNa with 90% content and ²⁴Na with 10% from ²H(²³Na, p)^24,24mNa, E=113 MeV at the John D. Fox Accelerator Laboratory of Florida State University]; measured reaction products, ionization chamber spectrum, production σ and compared with DWBA calculations, E(p), I(p), σ(θ) and compared with DWBA calculations. ²⁵Na; deduced levels, J, π, L-transfers, spectroscopic factors and compared with USDB shell-model calculations. ²⁵Na, ²⁵Si; compiled experimental levels, J, π, and compared with USDB shell-model calculations for A=25 system. ^24,24mAl(p, γ)²⁵Si, T=0.01-10 GK; deduced astrophysical reaction rates; evaluated contribution of the 1+ isomeric state in ²⁴Al to the ²⁴Al(p, γ)²⁵Si reaction rate, and compared with rates in REACLIB. Relevance to destruction of ²⁴Al via proton captures in its isomeric state in rp-process nucleosynthesis.
