|Abstract||Directional correlation experiments have been performed for the 1385- 885, 760-1510, and 940-885 kev gamma-ray cascades in Cd/sup 110/. Spins of 5, 6, 3, 4 have been assigned to the levels at 2935, 2490, 2170, and 1540 kev in the Cd/ sup 110/ level scheme. The 1355- and 1510-kev gamma rays are dipole-quadrupole mixtures. (auth) l647l LIGHT-PARTICLE SPECTRA FROM THE NITROGEN Energy spectra and angular distributions were measured for protons and alpha particles resulting from the nitrogen bombardment of oxygen. It was found that the angular distributions of protons are reasonably isotropic whereas alpha particles are peaked in the forward direction. The energy distributions at various angles were compared with the predictions of a simple level density formula w = C expSTA2(aE*)/sup 1/2/!. The constant a was found to be a = 2.5 plus or minus 0.2 from proton spectra, a == 1.3 plus or minus 0.2 from alpha -particle spectra at all angles measured. The energy spectrum of deuterons was measured at 15 deg and a value of a = l.8 plus or minus 0.3 was found. Unexplained structure was observed in the spectrum of alpha particles emitted at zero degrees. After correction for the phase space available and the barrier penetration, it was found that alpha particles are emitted on the order of ten times more copiously than protons, while deuterons are about half as abundant as protons.

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.
