Deuteron-gamma angular correlations in the reactions 24,26Mg, 28,30Si(d, d1γ) at Ed=10 MeV
Abstract
We measured differential cross sections and d1-γ angular correlations for the scattering of 10 MeV deuterons on 24Mg, 26Mg, 28Si, and 30Si. The data were analyzed in terms of coupled channels in a 0+-2+ coupling scheme on the basis of a symmetric rigid rotator model and in the framework of the distorted wave Born approximation. The correlation data of 24,26Mg show a remarkable prolateoblate sensitivity. They can be described also in the distorted wave Born approximation, but only in the prior interaction form. For 30Si multistep processes can be indicated. The results are consistent with a prolate nuclear shape of 30Si. NUCLEAR REACTIONS 24,26Mg 28,30Si(d, d'γ), Ed=10 MeV; measured inplane d1-γ correlations. 24,26Mg 28,30Si deduced prolate-oblate nuclear shape, restriction of optical model parameters. Coupled channels and DWBA analyses, enriched targets.
