STOPPING POWER AND THE SPREAD OF THE ENERGY LOSS OF CHARGED PAR-TICLES IN A DENSE ONE-COMPONENT PLASMA

Abstract

In this paper we consider the energy loss and the spread of the energy loss of charged particles in the electron liquid. The obtained results are compared with the data found by other authors in the framework of molecular dynamics modeling [1, 2]. In this paper, we use the method of moments [3], which allows to determine the stopping power and the spread of energy losses of the nonideal plasma, without using the expansion in the small parameter. The universality of this approach is to use different effective potentials of interparticle interaction for calculations.
The peculiarity of calculations using the method of moments is the need to determine the so-called parameter-function Nevanlinna included in the calculated ratio. In this article for this func-tion the relation offered by us earlier in [4].
An important advantage of this approach is the ability to determine the dynamic characteris-tics of Coulomb systems calculated by static characteristic, which can be found, for example, from the solution of the Ornstein-Zernike equation in the hyperchain approximation using the potentials specified in the work.
Keywords: one-component plasma, stopping power, range energy loss, method of moments, the Coulomb system, the Nevanlinna formula, loss function.
