摘要

本文研究了磁场中惯性约束聚变等离子体中电子-离子散射的过程。所提出的研究带电粒子之间散射过程的模型是基于求解考虑外部磁场的中心场中的运动方程,以及库仑对数,库仑对数是使用对碰撞中的散射角确定的。研究了电子和离子之间通过汤川势相互作用的碰撞。此外,还计算了磁场中稠密等离子体中的库仑对数。研究了考虑磁场对散射角、散射截面和库仑对数的影响。根据所获得的结果,可以确定,对于弱粒子相互作用,考虑磁场会导致散射角的非单调变化和散射截面的减小。研究还表明,对于相互作用参数β的大值,磁场不会影响库仑对数的值。因此,所获得的结果使我们能够研究在稠密等离子体中的外部恒定磁场中,在近似成对碰撞的情况下,考虑磁场对离子上电子散射过程的影响。

Investigation of the scattering of electrons by ions in the plasma of inertial confinement fusion in a magnetic field
In this paper, the processes of electron-ion scattering in the plasma of inertial confinement fusion in a magnetic field were studied. The proposed model for studying the processes of scattering between charged particles is based on solving the equation of motion in a central field taking into account the external magnetic field, as well as the Coulomb logarithm, which is determined using the scattering angle in a pair collision. Collisions between an electron and an ion that interact via the Yukawa potential were investigated. Also, the Coulomb logarithm in a dense plasma in a magnetic field was calculated. The effect of taking into account the magnetic field on the scattering angles, the scattering cross-section and the Coulomb logarithm are studied. From the results obtained, it is established that taking into account the magnetic field led to a non-monotonic change in the scattering angle and a decrease in the scattering cross-section for weak particle interactions. It is also revealed that for large values of the interaction parameterβ, the magnetic field does not affect the value of the Coulomb logarithm. Thus, the obtained results allow us to study the effect of taking into account the magnetic field on the processes of electron scattering on an ion in the approximation of pair collisions in an external constant magnetic field in a dense plasma.
