|Abstract||A millimicrosecond time-of-flight technique was applied io a study of the scattering of 2.2-Mev neutrons from targets of Fe, Pb/sup 206/,. and Y. The 3- Mev phasefocused proton beam from the BNL 18-inch cyclotron was used to produce high-intensity neutron pulses in ihe T(p,n)He/sup 3/ reaction. The angular distributions of the elastically scattered neuirons have been meas:ired for the above targets. The angular distributions of the inelastically scattered neutrons from the 0.845-Mev level in Fe/sup 56/ and from the 0.803-Mev level in Pb were carefully studied and found to be symmetric about theta /sub c.m. = 90 deg . The angular distributions of the inelastically scattered neutrons from levels at 1.34 and 1.43 Mev in Pb/sup 206/ and from levels at 0.913 and 1.53 Mev in Y were measured and also appear to be symmetric about theta /sup c.m./ = 90 deg The inelastic scattering from Pb/sup 206/ shows evidence for a new level at 1.15 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.
