We have produced an intense and pure beam of {sup 31}Cl with the MARS Separator at the Texas A and M University and studied {beta}-decay of {sup 31}Cl 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 {sup 31}Cl, 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.
