| Abstract | Summary form only given, as follows. A spherical pinch experiment is discussed in which a central spark is produced between two electrodes, carrying a current of the order of 100 kA under a voltage difference of the order of 10 kV. In order to obtain the X-ray spectra from plasmas, it is necessary to know in detail the spectrum of electrons in the presence of a strong electric field. The velocity spectrum of electrons results from the competing effects between the acceleration by the electric field and the deceleration by collisions. Coulomb interactions and binary short-range collisions are taken into account in the present work. Starting from one-dimensional time-independent Boltzmann Fokker-Planck equation, a spatially uniform plasma subjected to an electric field is considered. With an appropriate change of variables this equation is transformed into the confluent hypergeometric equation. The electron distribution function is then calculated in closed form together with the density current. |

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.
