The ( gamma ,p) and ( gamma , alpha ) reactions in argon were studied by irradiation of an Ar gas target with the bremsstrahlung beam of 31 Mev. Three different maximum bremsstrahlung energies were used: 23, 26, and 30 Mev. The charged photoparticles emitted at an angle around 90 deg with the gamma -ray beam were recorded by nuclear emulsion. Tracks with a total range <75 mu m of emulsion are attributed mainly to Ar( gamma , alpha ) process whose d sigma /d OMEGA is given. Thus the apparent anomaly disappears in the spectrum Ar( gamma ,p) with a high and narrow peak at energy lower than the Coulomb barrier. The ( gamma ,p) yield appears to be lower than that found by Spicer and McPherson, et al., while seeming to be in agreement with the work of Linderberger on the Ar( gamma ,p) cross section. (auth)
