|Abstract||Angular distributions for the Be/sup 9/(He/sup 3/,d)B/sup 10/, Be/sup 9/ (He/s up 3/,t)B/sup 9/, 41/ reactions were measured at 25 Mev and also at 21 Mev for the carbon reaction. It was found that the angular distributions were strongly peaked forward, exhibited diffraction-like structure, and were asymmetric about 90 deg . The minimal positions of the angular distributions could be fitted with spherical Bessel functions of the appropriate order 1, the angular momentum transfer of the ingoing proton. This analysis resulted in the same interaction radius for various levels in each of these reactions. The best- fit interaction radius for each cass was 6.17, 5.91, 6.23, and 7.29 fermis, respectively. The Butler stripping theory was also fitted to the angular distributions; however, the average decrease of the angular distributions did not agree with the predicted decrease except in one case. The reactions exhibited the general characteristics of a direct process and could be predicted qualitatively with the simple form of direct interaction theories. The experimental equipment and the method of data analysis, using computer codes, is described. The ground-state Q values were measured for the Ca/sup 40/(He/sup 3/ ,d)Sc/sup 41/ Ca/sup 40/(d,n)Sc/sup 41/, and O/sup 16/(He/sup 3/,d)F/sup 17/ reactions. Q valu es for levels excited by the Ca/sup 40/(He/sup 3/,d)Sc/sup 41/ reaction were also measured. (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.
