Yield measurements were performed on the reactions /sup 37/Cl(p,p/sub o/ )/sup 37/Cl, /sup 37/Cl(p, alpha /sub o/)/sup 34/S (E/sub p/ = 1.17 to 1.70 MeV) and /sup 37/Cl(p,n/sub o/)/sup 37/Ar, /sup 37/Cl(p, gamma )/sup 38/Ar (E/sub p/ = 0.64 to 2.92 MeV); detailed investigations are restricted to resonances below E/ sub p/ = 1. 79 MeV. Resonance energies, strengths and (some) widths are reported for 12, 26 and 247 resonances in the reactions (p,p/sub o/), (p,n/sub o/) and (p, gamma ), respectively Simultaneous (p, alpha /sub o/) and (p, gamma ) yield measurements over selected E/sub p intervals in the E/sub p/ - 0.88 to 1.64 MeV range established the existence of 42 resonances decaying by both gamma and alpha /sub o/ emission. Analysis of the gamma -ray spectra of 100 /sup 37/Cl(p, gamma )/sup 38/Ar resonances le ads to precision excitation energies ( DELTA E/ sub x/ = 0.1 to 2 keV) of 57 bound states (E/sub x/ < 8 MeV) and branching ratios of the resonances and of 50 bound states. (auth) correlation coefficients. Cross correlation coefficients between different reaction channels were calculated. (auth)
