Abstract

The angular distributions of elastically scattered deuterons on He4 have been measured at 21.3, 24.3, 25.8 and 27.3 MeV laboratory energy. Particularly at 21.3 MeV the shape is qualitatively consistent with some lower energy measurements, at 8 MeV and at 10.3 MeV, performed by Burge et al. and Allred et al., respectively. Between 24.3 and 27.3 MeV an additional oscillation in the elastic differential cross section is presumably related with the appearance of an F component, in addition to the S, P and D components, used to fit the data at lower energies by Gammel, Hill and Thaler, assuming a model of interaction of the nucleons of the deuteron with a He4 “lump” or “fundamental” particle. The angular distribution of the stripping reaction He4(d, p)He5 was also measured at 24.3 and 27.3 MeV. The residual nucleus is left in a virtual ground state and it is very short lived. The proton group seems to be the “head” of a continuum of the three body deuteron break up process. Some indications of an oscillatory behaviour of the differential cross section were obtained. Some reasonable PWBA fits were calculated for ln = 1 and strikingly small interaction radii, r0 = 1.2 fm at 27.3 MeV and r0 = 1.3 fm at 24.3 MeV. The corresponding reduced widths are θ2 = 0.0031 and θ2 = 0.0033, respectively.
