Abstract

The strength of the $E_{c . m .} = 184 keV$ resonance in the ${}^{26 g}{Al} (p, γ) {}^{27}{Si}$ reaction has been measured in inverse kinematics using the DRAGON recoil separator at TRIUMF’s ISAC facility. We measure a value of $ω γ = 35 \pm 7 μ eV$ and a resonance energy of $E_{c . m .} = 184 \pm 1 keV$ , consistent with $p$ -wave proton capture into the 7652(3) keV state in ${}^{27}{Si}$ , and discuss the implications of these values for ${}^{26 g}{Al}$ nucleosynthesis in typical oxygen-neon white-dwarf novae.
