Constraining the $^{30}$P(p,$\gamma$)$^{31}$S reaction using $^{30}$P(d,p$\gamma$)$^{31}$P with GODDESS
ORAL
Abstract
The $^{30}$P(p,$\gamma$)$^{31}$S reaction rate critically affects the mass flow into the A=30-40 range, impacting abundances of isotopes of P, S and Si during classical nova nucleosynthesis. This reaction rate depends on undetermined spectroscopic strengths of low-lying resonances in $^{31}$S, lying between 6 and 7 MeV in excitation. But, direct measurement of (p,$\gamma$) reaction is not possible due to low intensities of currently available $^{30}$P beam and proton spectroscopic factors on unstable nuclei are difficult to measure experimentally. We performed a $^{30}$P(d,p$\gamma$)$^{31}$P reaction measurement using the newly commissioned GODDESS (Gretina-ORRUBA: Dual Detectors for Experimental Structure Studies) system-with an 8 MeV/u $^{30}$P beam, from RAISOR at ATLAS, to provide constraints on the proton spectroscopic strengths for $^{31}$S levels via mirror symmetry. Experimental details and data analysis status will be presented.
