Abstract
The angular distribution and the direction-polarization of the 440–keV gamma rays in 23 Na( p , p 'γ) 23 Na reaction have been measured at the 1.29-MeV resonance. For these measurements the following results were observed; for the angular distribution, W (θ)=1-(0.091±0.004) P 2 (cos θ) and for the polarization parameter, p =+0.69±0.02. From the observed results, the mixing ratio of the 440-keV gamma radiation was obtained as (E2/M1) 1/2 =+0.045±0.015. This value agrees with the prediction from the collective model.Keywords
