Measurement of the E{sub c.m.}=184 keV Resonance Strength in the {sup 26g}Al(p,{gamma}){sup 27}Si Reaction

The strength of the E{sub c.m.}=184 keV resonance in the {sup 26g}Al(p,{gamma}){sup 27}Si reaction has been measured in inverse kinematics using the DRAGON recoil separator at TRIUMF's ISAC facility. We measure a value of {omega}{gamma}=35{+-}7 {mu}eV and a resonance energy of E{sub c.m.}=184{+...

Description
Summary:The strength of the E{sub c.m.}=184 keV resonance in the {sup 26g}Al(p,{gamma}){sup 27}Si reaction has been measured in inverse kinematics using the DRAGON recoil separator at TRIUMF's ISAC facility. We measure a value of {omega}{gamma}=35{+-}7 {mu}eV and a resonance energy of E{sub c.m.}=184{+-}1 keV, consistent with p-wave proton capture into the 7652(3) keV state in {sup 27}Si, and discuss the implications of these values for {sup 26g}Al nucleosynthesis in typical oxygen-neon white-dwarf novae.
