Abstract # 91
(p,t) Reactions on N=Z Target Nuclei at Ep=100 MeV
24Mg(p,t)22Mg, 28Si(p,t)26Si, 32S(p,t)30S, 36Ar(p,t)34Ar, 40Ca(p,t)38Ca
Physics Motivation and Experimental Method
Nuclear structure of unstable proton-rich nuclei
Measure precise resonance energies above the
p- and α- thresholds using the high-resolution
GRAND RAIDEN spectrometer (10 – 50 keV)
Calculate improved stellar reaction rates,
determine paths of astrophysics rp process in hot
hydrogen burning in e.g. novae and X-ray bursters
Result:
Statistical level density model (Hauser-Feshbach) overestimates stellar reaction rates
32S(p,t )30Si, Ep = 100 MeV
p threshold
α threshold
