The reaction {sup 36}Ar({ital p},{gamma}){sup 37}K has been measured in the proton energy range of {ital E}{sub {ital p}}=0.32--0.93 MeV. A new resonance was found at {ital E}{sub {ital R}}=321 keV. We have measured the branching ratios and the resonance strength. The stellar reaction rates which are dominated by this resonance for temperatures {ital T}=0.07--0.9 GK are calculated. Network calculations have been performed to investigate the influence of the new stellar rates on the time evolution of the {sup 36}Ar abundance during explosive H burning.
