The differential cross sections of tritons from the (d, t) reaction on9Be,10B and13C targets have been measured in the angular range of 5°≦ϑLAB≦110° with relatively small errors, ∼ 5%. The experimental data were analysed in terms of the standard DWBA using both zero-range and exact finite-range approaches.

The angular distributions of the (p, d) reactions on the7Li,9Be and13C nuclei have been analysed within the framework of the new approach to the extraction of the structural information from the direct nuclear reactions. In this method the additional physical information on the nuclear vertex constants is introduced into the standard DWBA calculations, which makes possible to eliminate the strong dependence of the spectroscopic factors on the geometry of bound state potentials. The possibility of the model — independent determination of the spectroscopic factors — is discussed.

We report precision measurements and analysis of the differential cross sections for (p,d) reactions in /sup 7/Li, /sup 9/Be, and /sup 13/C at energy E/sub p/ = 18.6 MeV. The accuracy achieved in measurement of the cross sections is 5% or better. The region of angles from 5 to 120/sup 0/ is covered. As the result of analysis according to the peripheral model and by the method of extrapolation to a pole we have obtained corresponding nuclear vertex constants. Analysis of the angular distributions by the distorted-wave Born approximation with use of additional information on the nuclear vertex constants has given spectroscopic factors which in some cases differ greatly from the shell spectroscopic factors and from values obtained in the ordinary DWBA procedure.
