| Abstract | LSO:Ce and LYSO:Ce has been proposed as a perspective pre-shower detector for search for /spl mu/+/spl rarr/e/sup +/ /spl gamma/ decay with the branching-ratio sensitivity of 10/sup -14/ at PSI (Villigen, Switzerland). The detection involves 52.8 MeV /spl gamma/-rays. To study the response of the crystals to high energy /spl gamma/-rays we have chosen Pu-Be neutron source which due to a /sup 9/Be(/spl alpha/,n) reaction gives monoenergetic 4.439 MeV /spl gamma/-rays. We have studied the response of /spl phi/60/spl times/10 mm YSO:0.2%Ce crystal and half disk of /spl phi/60/spl times/10 mm LSO:0.2%Ce. Despite the large background of /sup 176/Lu the high energy /spl gamma/-rays can be detected efficiently. We have also studied the response to lower energy /spl gamma/-rays (from /sup 137/Cs and /sup 60/Co sources) and found the conditions of optimum work, YSO crystal detects 4.439 MeV /spl gamma/-rays primarily by double 511 keV escapes that form a distinct peak on energy spectrum. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built 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 designed 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 developed, operated and maintained from 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 Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
