Study of Excited States of S-31 Through Beta-Decay of Cl-31 for Nucleosynthesis in One Novae

We have produced an intense and pure beam of Cl-31 with the MARS Separator at the Texas A&M University and studied beta-decay of Cl-31 by implanting the beam into a novel detector setup, capable of measuring beta-delayed protons and gamma-rays simultaneously. From our data, we have established decay scheme of Cl-31, found resonance energies with 1 keV precision, have measured its half-life with under 1% accuracy, found its Isobar Analog State decay and by using the IMME obtained an improved mass excess for its ground state. In this contribution, a description of the used method along with selected preliminary experimental results are given and their relevance for novae nucleosynthesis discussed.
