Indirect Studies of (α,p) Reactions along the αp-Process Path and their Influence on Type 1 X-ray Burst Light Curves

The 30S(α,p) and 34Ar(α,p) reactions have both been identified in serval Type-1 X-ray Bursts (XRBs) sensitivity studies as significant influential reactions within the αp-process. According to 1-D XRB models, the strength of these two reactions can affect not only final abundance patterns XRB ashes, but also possibly the bolometric shapes of double-peaked XRB light curves. Given the lifetimes of the nuclei involve, very little experimental information exists for these two reactions, therefore, XRB models depend on a statistical Hauser-Feshbach (HF) model to predict the reaction rate. Recently, questions on the reliability of HF predicted rates for these reactions arise due to level density considerations in the compound nuclei ( 34Ar and 38Ca).
