Abstract

The capture reaction ²⁶Al(p, γ)²⁷Si has been investigated in the energy range of E_p = 0.17–1.58 MeV. High-spin resonances were found at E_R = 287, 376, 719, 727, 790, 856 and 927 keV. Resonances for the reaction ²⁶Al(p, p₂γ)²⁶Al were observed at E_R = 927, 1122, 1252 and 1363 keV. Information on resonance energies, total widths, branching ratios and resonance strengths is reported. The investigated energy range corresponds to the stellar temperature region of T = (0.2–1.0) × 10⁹ K. The deduced stellar reaction rates are used to calculate the abundance of ²⁶Al in the hydrogen burning MgAl cycle.

A compilation of charged-particle induced thermonuclear reaction rates
1999, Nuclear Physics A
Low-energy cross section data for 86 charged-particle induced reactions involving light (1 ⩽ Z ⩽ 14), mostly stable, nuclei are compiled. The corresponding Maxwellian-averaged thermonuclear reaction rates of relevance in astrophysical plasmas at temperatures in the range from 10⁶ K to 10¹⁰ K are calculated. These evaluations assume either that the target nuclei are in their ground state, or that the target states are thermally populated following a Maxwell-Boltzmann distribution, except in some cases involving isomeric states.
Adopted values complemented with lower and upper limits of the rates are presented in tabular form. Analytical approximations to the adopted rates, as well as to the inverse/direct rate ratios, are provided.
