| Abstract | Summary form only given. Considers plasmas produced by the action of a high-intensity (more than 10 to the power of 16 Watt per centimeter squared) ultrashort-pulse (less than 10 to the power of -12 second) laser radiation on a solid target. In the case of the laser-produced plasmas one has to do with stabilities (of atoms and nuclei), as well as with unstabilities, i.e. collective processes at all stages of laser-produced plasma development. The collective processes play the decisive role in the laser-produced plasmas. This is the reason for representation of plasma of the sort as a quantum object. The laser-produced plasma is determined by the presence of electronic spin. In this case the electronic spin dictates the statistics, i.e. the collective nature of the processes. Hence follows the linkage between the concept or collective processes, i.e. instabilities involved in the plasma theory, and the concept of pure ensembles in use in the quantum mechanics. Here arises the concept of spin plasma. The essence of our model for transformation of energy of laser radiation incident on the target into the energy which gives rise to nuclear transformations in the target material is outlined. The mechanism of superstrong magnetic field energy transformation into the energy of atomic and nuclear systems excitation in a laser-produced plasma are studied. It is demonstrated that the transformation of such fields by atomic structures leads to the generation of magnetic fields in an atom, which destroy the internal structure of low-lying electronic shells and give rise to the wave collapse, or "nucleation", of the fields with subsequent strong action on nuclei. |

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.
