Abstract / Description of output

We have produced an intense and pure beam of Cl with the MARS Separator at the Texas A&M University and studied β-decay of Cl by implanting the beam into a novel detector setup, capable of measuring β-delayed protons and γ-rays simultaneously. From our data, we have established decay scheme of 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.
