| Abstract | Studies are reported on the possibility of detection and spectrometry of thermal and resonance neutrons using crystals based on complex oxides. The crystals studied included CWO, GSO(Ce), NBWO, polycrystals LuSO(Ce), comprising elements Cd, Gd, W, Lu, Na with large capture cross-section of thermal and resonance neutrons. Energy spectra have been studied for products of nuclear reactions of internal conversion electrons (ICE), KX- and gamma-quanta in said compounds. A possibility has been shown in principle of spectrometry of thermal neutrons on nuclei of the said elements in different energy ranges, with exception of /sup 176/Lu nuclei. The presence of radiation background froth the nuclei of natural radionuclide /sup 176/Lu, as well as high induced activity due to radiation neutron capture, can be additional sources of the background. Induced activity spectra were studied for NBWO crystals, and possibilities are discussed of their use as elements of optical system of combined neutron detectors. A possibility is shown to discern products of neutron radiation capture nuclear reactions on nuclei of cadmium, tungsten, gadolinium. This is achieved by means of selected energy detection windows for nuclear reaction products and accompanying gamma-radiation, using scintillators with different response times and interaction cross-sections with neutrons and gamma-quanta, as well as using screens that selectively absorb neutrons or gamma-quanta. |

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.
