MICRO-FIELD AND THERMAL PHYSICAL PROPERTIES OF NON-IDEAL PLASMA

Models of an electric micro-field in non-ideal, multicomponent plasma are investigated in the paper aiming at the construction of theoretical models of a micro-field for strong non-ideal plasma; the development of simple and exact approximations for the used models of a plasma micro-field; the development of effective numerical algorithms for the calculation of the micro-field distribution; the creation of a complex of applied programs. As a result a new model of a polarized discharge for an ionic component of a micro-field in non-ideal plasma of complex composition has been constructed. The model modification of simple harmonic oscillators has been obtained for the distribution of a micro-field in superdense plasma in the vicinity of a neutral atom. Analytical approximations for Fourier-image of a function of the micro-field distribution, approximations applied to plasma of complex composition, have been obtained. Calculation algorithms for a function of the micro-field distribution in plasma of complex composition, algorithms more quicker for tens thousands times than the methods, used earlier, have been developed on the base of these approximations. Simple and convenient approximations have been found for the most important physical values (the mean decrease of the ionization potential, width and shift of a spectral line in ionic micro-fields). The paper results may find their field of application in investigations of thermal physical and optical properties of dense, non-ideal plasma; problems of the controlled thermonuclear synthesis and the radiation interaction with a matterAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
