|Abstract||ABS>The conversion electron spectrum of /sup 182/W was measured by means of an iron-yoke double-focusing spectrometer. By careful analysis of the conversion spectrum, which was recorded at a resolution of about 0.28%, it was possible to identify two additional new transitions of 146 and 351 kev gamma rays not reported before. Multipolarities and mixing ratios were determined from K/L or L-subshell ratios for low-energy transitions. The determined conversion coefficients generally support previous spin assignments. The 116-kev gamma transition was found to be an electric dipole transition, while the 146kev gamma ray has magnetic quadrupole character. New levels at 680 and 1437 kev with spin and parity 6/sup +/ and 4/sup +/, respectively, were confirmed. No penetration effects were found in the conversion process of the retarded 67-, 116-, and 222- kev E1 transitions. However, the retarded 152-, and 156-kev electric dipole transitions showed an anomalous internal conversion coefficient deviating about 20% from the theoretical values for pure E1 transitions calculated by Sliv and Band.

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.
