Resum
Proton-unbound excited states of 31S have been populated with the 32S(d,t)31S reaction at a beam energy of 24 MeV. Tritons corresponding to 31S states with Ex (31S)˜6.3-7.1 MeV were momentum analyzed with a high resolution quadrupole-dipole-dipole-dipole (Q3D) magnetic spectrograph at six angles ranging from ¿lab=15 â^~ to 58.5â^~. We report a statistically significant detection of an astrophysically important state at Ex (31S)=6402 (2) keV, whose existence as a third state in this region ha...
