Abstract

A three-body classical trajectory Monte Carlo method is used to calculate the nl state-selective charge exchange cross sections in hbox {Be}^{mathrm {4+}}+ H(2lm) collisions in the energy range between 10 and 200 keV/amu. We present partial cross sections for charge exchange into hbox {Be}^{mathrm {3+}}(nl) (textit{nl} = 2s, 2p, 3s, 3p, 3d, 4s, 4p, 4d, 4f) states as a function of impact energy. Our results are compared with the previous classical and quantum-mechanical results. We show that the classical treatment can able to describe reasonably well the charge exchange cross sections.Graphic abstract

Summary

Introduction

One of the most critical industries that secure the future of human energy is the nuclear industry Fusion reactors such as the International Thermonuclear Experimental Reactor (ITER) have been developed to produce and confine the plasma [1]. Beryllium ions can collide with the ground and excited state of the hydrogen atoms; the accurate knowledge of these reaction cross sections are essential in fusion research. The classical trajectory Monte Carlo method has succeeded in dealing with the charge exchange processes in ion atom collisions [3,12]. We focus on the charge exchange cross sections in collisions between Be4+ and excited state hydrogen atoms, H(n,l,m). Calculations are made using the three-body classical trajectory Monte Carlo method for impact energies between 10 and 200 keV/amu. Since there is no experimental data in Be4+ and H(2lm) collision system, we compare our results with the previous theoretical results
