Low energy proton capture resonances in the chlorine isotopes

A search was made for proton capture resonances in the chlorine isotopes, making use of natural and enriched targets. Eighteen resonances have been observed in the proton energy region from 300 to 900 keV, and their isotopic assignment has been established from a comparison of the yield curves. Single gamma-ray spectra have been recorded at all resonances. The characteristic lines observed in the spectra confirmed the isotopic assignment, made from the yield curves. Gamma-ray yields are given in absolute measure. Branching ratios have been measured for transitions to known 36A and 38A levels
