Improving the P30(p,γ)S31 rate in oxygen-neon novae: Constraints on Jπ values for proton-threshold states in S31
Abstract
Calculation of the thermonuclear P30(p,γ)S31 rate in oxygen-neon nova explosions depends critically upon nuclear structure information for states within ∼600 keV of the 30P+p threshold in S31. We have studied the P31(3He,t)S31 reaction at 25 MeV using a high-resolution quadrupole-dipole-dipole-dipole magnetic spectrograph. Tritons corresponding to the states Ex(S31) ∼ 6.1–7.1 MeV were observed at ten angles between θlab = 10° and 55°. States …
