摘要
借助于线性Vlasov方程,我们研究了重离子束在等离子体靶中的有效电荷数和电子阻止本领。在高速情况下,分别得到了它们的解析表示式。以^(40)Ga,^(74)Ge,^(84)Kr,^(110)pd,^(208)pb及^(238)U等重离子束在氢等离子体中的能量损失为例,将我们的理论结果与Hoffmann等人的实验结果进行了比较。
Using the linear Vlasov equation, we have investigated the effective charges of ion beams and electron stopping ability in plasma targets. Analytical expressions of electron stopping ability and effective charge are obtained. The theoretical values in our work are comparied with the experimental data of Hoffmann et al. for the energy losses of the heavy ions, i.e.Ga, Ge, Kr, Pd, Pb and U in hydrogen plasma.
