Kernreaktionen durch Deuteronen von 52 MeV

Abstract

The nuclear reactions of 52 MeV deuterons have been studied at some medium weight and heavy nuclei. The angular distributions of elastically scattered deuterons show sharp structures which are smoothed out — similar to the results at lower deuteron energies — for target nuclei near A = 100. The optical model analysis gives good fits with parameters extrapolated from the best values at lower energies. The „Smoothed Cut-off“ models do not describe the results properly. The influence of the nuclear interior on the elastic scattering is important. The proton spectra from the (d, p) and (d, pn) reactions are dominated by a broad „break up“ maximum. From the width of the maximum and the A-dependence of the cross section it is concluded that nuclear break up is more frequent at 52 MeV than COULOMB break up. The spectra of deuterons and tritons from the (d, d′) and (d, t) reactions show maxima up to Q-values of — 15 MeV. With these reactions it should be possible to study collective excitation up to high excitation energies and to get information about inner shells. The intensity of low energy inelastic deuterons is surprisingly large.
