|Abstract||The radioactive decay of the isomers of Ag/sup 104/ was investigated using scintillation spectrometers and a magnetic BETA ray spectrometer. Half lives of (66 plus or minus 1) and (29.8 plus or minus 0.5) minutes were determined for the spin 5 and spin 2 isomers, respectively. Conversion electrons corresponding to 15 gamma rays assigned to Pd/sup 104/ were observed. Two allowed positron transitions were detected: one of end-point energy (990 plus or minus 10) kev from the spin 5 isomer of Ag/sup 104/; and the other of end-point energy (2705 plus or minus 15) kev from the spin 2 isomer. Gamma-gamma and BETA - gamma coincidences were observed. The experimental data together with data obtained by other investigators were used to determine the spins and parities of the low-lying excited states of Pd/sup 104/. (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.
