Mass of astrophysically relevant ³¹Cl and the breakdown of the isobaric multiplet mass equation

ATOMIC MASSES ³¹Cl; measured TOF-ICR spectrum, and mass excess using JYFLTRAP double-Penning-trap mass spectrometer at the IGISOL facility in Jvyaskyla; analyzed isobaric multiplet mass equation (IMME) for T=3/2 quartet for A=31 nuclei ³¹Cl, ³¹S, ³¹P and ³¹Si; deduced breakdown of the IMME. ³¹Cl; deduced S(p), levels.

NUCLEAR REACTIONS ³²S(p, 2n)³¹Cl, E=40 MeV; measured mass excess of ³¹Cl at the IGISOL facility in Jvyaskyla. ³¹Cl(γ, p)³⁰S, T₉=0.2-1.4; deduced reaction rates for typical XRB conditions. Relevance to rapid proton capture process in type-I x-ray bursts.
