Proton partial widths evaluation through the 30 Si( 3 He, d ) 31 P transfer reaction for understanding abundance anomalies in Globular Clusters

Some observed abundances in globular clusters have suggested the existence of multiple generations of stars within the clusters as the observations require temperature ranges higher than current stars. The 30 Si( p ,γ) 31 P reaction plays a key role in the synthesis of the observed abundances. The study of the 30 Si( 3 He, d ) 31 P transfer reaction is a tool for constraining the strengths of low-lying resonances, and the proton partial widths are the main ingredients for calculating those strengths. We present the method used for estimating the proton partial widths and their associated uncertainties.
