Measurement of 26Al(d,p)27Al to constrain the 26Al(p,gamma) reaction rate*

The galactic mapping of the 1809-keV $\gamma$ ray from the beta decay of $^{26}$Al has provided an insight into ongoing galactic nucleosynthesis. Understanding the abundance of $^{26}$Al requires knowledge of rate of destruction of $^{26}$Al, partially via the $^{26}$Al(p,$\gamma$)$^{27}$Si reaction, which is determined by states near the proton threshold in $^{27}$Si. Due to the difficulty of measuring these resonances directly, an alternative is to measure mirror states in $^{27}$Al to inform the $^{27}$Si structure. The spectroscopic strengths of a few known mirror states are the dominant sources uncertainty in the $^{26}$Al(p,$\gamma$)$^{27}$Si reaction rate. The $^{26}$Al(d,p)$^{27}$Al reaction has been measured in inverse kinematics at the HRIBF. A beam of $\sim$5 million $^{26}$Al per second impinged on a $\sim$150 $\mu$g/cm$^2$ CD$_2$ target. Proton ejectiles were detected in the SIDAR and ORRUBA silicon detector arrays. Details of the experimental setup and data analysis will be presented.
