First measurement of the 33 Cl( p , α ) 30 S reaction

Abstract

Physical Review C 84, 045802 (2011) /// The 30S(alpha; p)33Cl reaction may have a significant impact on final elemental abundances and energy output of type I X-ray bursts, as well as influencing observables such as double-peaked luminosity profiles, as it could bypass the 30S waiting point. This reaction has been studied experimentally for the first time in inverse kinematics via the time-inverse reaction p(33Cl,30S)alpha with a 33Cl radioactive ion beam produced at the ATLAS facility by the "in-flight" technique. This reaction was studied at three different beam energies. The experimental method used and the resulting data are discussed.
