Abstract

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 ³⁰Si(p,γ)³¹P reaction plays a key role in the synthesis of the observed abundances. The study of the ³⁰Si(³He,d)³¹P 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.
