Title: Measurement of {sup 25}Al+p resonant elastic scattering for studying the {sup 25}Al(p,{gamma}){sup 26}Si

Abstract

Proton resonant states in {sup 26}Si have been studied by the resonant elastic scattering of {sup 25}Al+p with a {sup 25}Al radioactive ion beam at 2.863 MeV/nucleon bombarding a thick H{sub 2} gas target with the inverse kinematics method at the low-energy RI beam facility CRIB (CNS Radioactive Ion Beam separator), University of Tokyo. The properties of these resonance states are important to better determine the production rates of {sup 25}Al(p,{gamma}){sup 26}Si reaction, which is one of the astrophysically important nuclear reactions to understand the production of the ground state of {sup 26}Al, the emitter of its characteristic 1.809-MeV gamma-ray, under the explosive stellar environments such as novae and X-ray bursts. In this work, several resonances above the proton threshold level have been observed with a high statistics and background free through a covered the range of excitation energies from E{sub x}{approx} 6.8 to 8.2 MeV.
