In recent years, there has been a lot of interest in studying transfer reactions and heavy ion induced reactions provide a wide opportunity for studying various transfer channels. Recently, we have studied one nucleon transfer (proton transfer) in the reaction 12C+27Al which ends up with 11B+28Si as exit channel. The experiment was carried out at BARC-TIFR 14UD Pelletron Accelerator Laboratory, Mumbai, India using 73 MeV 12C ion beam on 27Al target. The thickness of the self-supporting 27Al target was 545 microgm/cm2. Emitted fragments have been detected in Si-Si telescope in a wide angular range. The solid angle coverage was 2.26x10-4 sr. The distance of the telescope from the target was 20.9 cm. The well separated ridges corresponding to different fragments are clearly seen in E-E scatter plot. Here, in this paper, the scattering of 11B from different states of 28Si will be presented.
The experimental data have been analyzed with the software LAMPS. The experimental angular distributions of ground state 11B scattered from 0+ state of 28Si obtained from the reaction 12C on 27Al have been found. The theoretical finite range distorted wave Born-approximation calculations have been done using the code DWUCK5. The required optical model potential parameters were extracted by fitting the elastic angular distribution data for the systems 12C+27Al (entrance channel) [1] and 11B+28Si (exit channel) [2] respectively using the code ECIS94. Though the theoretical DWBA calculation reproduces the shape of the experimental angular distributions for the ground, first and second excited state very well, still they vary in magnitude. DWBA calculation underpredicts the differential scattering cross sections.
