Transfer reactions induced by 12C ON 18O and 26Mg AT 46 MeV

Angular distributions of levels observed in the 18O(12C, 10Be)20Ne, 26Mg(12C, 11B)27Al, 26Mg(12C, 10Be)28Si and 26Mg(12C, 9Be)29Si reactions have been measured at 46 MeV incident energy; some of them show a strong oscillating pattern. Spectroscopic factors extracted from a DWBA analysis of the (12C, 11B) 1p transfer with the LOLA code, are consistent with those derived from (3He, d). The influence of recoil effects on both the shapes of the angular distributions and the absolute magnitudes of cross sections have been studied for (12C, 11B) and (16O, 15N). The 2p transfer reactions leading to 20Ne and 28Si have been analyzed using realistic microscopic wave functions. Effects of configuration mixings on both the relative and the absolute cross sections are presented. The validity of approximating the 2p wave function by a 0s cluster component is discussed and some nuclear structure information is derived. The 26Mg(12C, 9Be)29Si reaction populates preferentially the same levels as the 28Si(d, p)29Si reaction. A DWBA analysis using a 3He cluster form factor gives relative spectroscopic strengths close to those derived from (d, p) stripping.
