S. Vouzoukas et al., REACTION-RATE FOR S-31(P,GAMMA)CL-32 AND ITS INFLUENCE ON THE SIP CYCLE IN HOT STELLAR HYDROGEN BURNING, Physical review. C. Nuclear physics, 50(2), 1994, pp. 1185-1193
The excitation energies of the proton unbound states in Cl-32 have bee
n measured in the S-32(He-3,t)Cl-32 charge exchange reaction with high
accuracy. The partial widths of the unbound levels have been calculat
ed to derive the resonance strengths of these states in the S-31(p,gam
ma)Cl-32 reaction channel. The reaction rate for the S-31(p, gamma)Cl-
32 reaction has been calculated and is compared with previous estimate
s. The role of this reaction for the closure of the SiP cycle is discu
ssed in terms of the temperature and density conditions in hot stellar
hydrogen burning.
