Notizen: Abstract Excitation functions were measured from 0.7 to 2.2 MeV for the α0 -, α1-, α2- and α3-groups at an angle ofθ L=90°. Two broad maxima were found in all four cases, suggesting the existance of resonances in the13C-compound nucleus. A problem, however, arises, as the first maximum appears at a bombarding energy of 1.15 MeV for the α0- and α1-groups, whilst it is shifted to 1.35 MeV in the excitation curves for the α2- and α3-groups. The second maximum appears at 1.85 MeV in all curves. Angular distributions were measured at 7 energies between 1.0 and 2.2 MeV for the α0- and α2-transitions. The coefficients of the first four Legendre polinomials, describing these distributions, are given.

Notizen: Abstract The excitation curve for the elastic scattering of deuterons from10B in the energy range from 1.0 to 2.0 MeV has been measured atθ L =135°. Strong indications for compound nucleus resonances in12C at bombarding energies of approximately 1.0 and 1.9 MeV were observed. Angular distributions from 80 to 175° were determined in 200 keV steps from 1.0 to 2.0 MeV. Optical model analysis were made both for volume absorption and surface absorption potentials. Reasonable fits were obtained at energies up to 1.6 MeV with one set of parameters in both cases, whilst for the higher energies strong deviations were found with the same parameters.

Notizen: Abstract Angular distributions of the α0-group and the α1-group were measured at 6 energies between 0.5 and 1.0 MeV and the coefficients of the Legendre polinomials have been calculated. Also given are relative cross section curves for the two α-groups between 0.5 and 2.0 MeV. The possibility of explaining the α0-excitation curve by assuming only a few broad compound state resonances is discussed.
