摘要：
Angular distributions for elastic α-particle scattering on 39K have been measured over the angular range θ = 20°-179° c.m. at Eα = 22.1, 23.1, 23.6, 24.0, 24.6, 25.5, 26.5, 27.4 and 28.2 MeV. A strong increase of the cross section was observed at the backward scattering angles with a well-developed oscillatory character. The experimental data are fitted with the semiclassical diffraction model at forward angles and the glory scattering model at backward angles. A difference of about 1 fm in radius parameters was found for the two models. © 1969.
