Measurement of the resonance at ER=1422 keV in Ar36(p,γ)37K

Abstract

A new resonance at ER=1422 keV has been found in the reaction Ar36(p,γ)37K. From its measured resonance strength of ωγ=(6.0±1.5)×10-4 eV the proton partial width Γp can be calculated. Our data suggest a value of Γγ/Γp40 for the ratio of γ to proton partial width for the corresponding state at Ex=3241 keV in K37. We find that the corrected distribution of Gamow-Teller strength below the isobaric analog state as obtained from the β-delayed proton decay of Ca37 is in agreement with the results inferred from the Cl37(p,n)37Ar reaction
