论文摘要
我们介绍了对称$ \ textrm {xe}^{54+}+\ textrm {xe} $在50、30和15 meV/u的碰撞的实验和理论研究速度，$ v_ \ text {p} $：弹丸速度），以及$ \ textrm {xe}^{53+}+\ textrm {xe} $ collisions $ collisions in 15 mev/u。对于这些系统中的每一个，相对于弹丸梁，X射线光谱的正向角度为$ 35^\ circ $。靶卫星和高卫星辐射，分别分析并用于得出双向目标$ k $ -sshell foldancy生产的$kα_{2,1}^\ mathrm {s} $和$kα_{2,1}^\ mathrm {hs} $。我们将实验结果与相对论时间依赖性的两个中心计算进行比较。
We present an experimental and theoretical study of symmetric $\textrm{Xe}^{54+}+\textrm{Xe}$ collisions at 50, 30, and 15 MeV/u, corresponding to strong perturbations with $v_K/v_\text{p}$ = 1.20, 1.55, and 2.20, respectively ($v_K$: classical $K$-shell orbital velocity, $v_\text{p}$: projectile velocity), as well as $\textrm{Xe}^{53+}+\textrm{Xe}$ collisions at 15 MeV/u. For each of these systems, x-ray spectra were measured under a forward angle of $35^\circ$ with respect to the projectile beam. Target satellite and hypersatellite radiation, $Kα_{2,1}^\mathrm{s}$ and $Kα_{2,1}^\mathrm{hs}$, respectively, were analyzed and used to derive cross section ratios for double-to-single target $K$-shell vacancy production. We compare our experimental results to relativistic time-dependent two-center calculations.
