Abstract
Systematic differences between measurements of excitation energies and branching ratios of unbound Cl levels near the proton threshold have recently emerged. We investigate these Cl properties using independent information by analyzing existing Ar()Cl data and using published values from measurements of the S(He,)Cl reaction. Significant evidence emerges in support of particular values. The results increase the thermonuclear rate of the S()Cl reaction by up to a factor of 2 over the temperature range of 0.4 to 2 GK that is reached during type I x-ray bursts on hydrogen-accreting neutron stars.
