|Abstract||The reaction /sup 12/C(p,p' gamma )/sup 12/C involving the first excited state at 4.93 Mev was investigated experimentally by measurements of the p'- gamma correlation and the proton angular distribution for an incident energy of 8.5 Mev. Although this energy corresponds to a region having no sharp resonances, the experimental results show that none of the simple models of the reaction mechanism are valid, because of the important contributions from proton spinflip during the inelastic scattering. The simplified distorted-wave theory of direct interactions is improved by including the effects of spin-orbit distortion, and an attempt is made to explain all the available data at 8.5 Mev. Partial success is achieved, and it appears that the inelastic scattering in this energy region is dominated by a direct interaction mechanism. The inclusion of spin-orbit distortion is found to be important. In contrast to previous work the correlation function is found to be relatively insensitive to the detailed nature of the target-nucleus wave functions. (auth)|

Ministry of Human Resource Development (MHRD) under its National Mission on Education through Information and Communication Technology (NMEICT) has initiated the National Digital Library of India (NDLI) project to develop a framework of virtual repository of learning resources with a single-window search facility. Filtered and federated searching is employed to facilitate focused searching so that learners can find out the right resource with least effort and in minimum time. NDLI is designed to hold content of any language and provides interface support for leading vernacular languages, (currently Hindi, Bengali and several other languages are available). It is designed to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is being developed to help students to prepare for entrance and competitive examinations, to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is being developed at Indian Institute of Technology Kharagpur.
NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Human Resource Development (MHRD), through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
