|Abstract||The mechanism of the O/sup 16/(He/sup 3/,p gamma )F/sup 18/ reaction proceeding via the first excited state of F/sup 18/ at 0.934-Mev excitation was studied by measuring the angular correlation in the plane of the reaction of the de-excitation gamma rays in coincidence with the proton group leading to this state. Correlations were measured at a fixed proton angle of 36 deg with incident He/sup 3/ energies of 9.16 and 10.0 Mev and also at a proton angle of 71 deg with an incident beam energy of 10.0 Mev. With the proton counter on the peak of the stripping curve at 36 deg , an axis of symmetry was found about 26 deg from the direction of the recoiling F/sup 18/ nucleus. The correlations are analyzed and discussed and are presented as favoring the two nucleon stripping process, where the two nucleons are captured as a lump, as being the predominant reaction mechanism for the O/sup 16/(He/sup 3/,p)F/sup 18/ reaction at a bombarding energy of about 10 Mev.

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.
