Target electron removal in C5+ + H collision

Saed J. Al Atawneh, K. Tőkési2022年被引用 4Nuclear FusionIF 3出版社

We present target ionization and charge exchange cross sections in a collision between C5+ ion and H atom. We treat the collision dynamics classically using a four-body classical trajectory Monte Carlo (CTMC) and a four-body quasi-classical Monte Carlo (QCTMC) model when the Heisenberg correction term is added to the standard CTMC model via model potential. The calculations were performed in the projectile energy range between 1.0 keV/amu and 10 MeV/amu. We found that the cross sections obtained by the QCTMC model are higher than that of the cross sections calculated by the standard CTMC model and these cross sections are closer to the previous experimental and theoretical data. Moreover, for the case of ionization, we show that the interaction between the projectile and the target electrons plays a dominant role in the enhancement of the cross sections at lower energies.

我々は、C5+イオンとH原子の衝突における標的電離断面積と電荷交換断面積を提示する。衝突ダイナミクスは、標準的なCTMCモデルにハイゼンベルク補正項をモデルポテンシャルとして付加した4体系古典軌道モンテカルロ法(CTMC)および4体系準古典軌道モンテカルロ法(QCTMC)を用いて古典的に扱う。計算は、入射粒子エネルギー1.0 keV/amuから10 MeV/amuの範囲で行った。QCTMCモデルによって得られた断面積は、標準的なCTMCモデルによって計算された断面積よりも高く、これらの断面積は先行の実験データおよび理論データにより近いことが判明した。さらに、電離の場合について、入射粒子と標的電子の間の相互作用が、低エネルギー領域における断面積の増大に支配的な役割を果たすことを示す。
