论文摘要
由重离子（HI）融合蒸发反应产生的高度电离重型蒸发残基（ER）从固体靶标敲出到充气后坐力分离器的稀有气体。在天然气中，这些ERS在通往检测系统的途中经历了收费的碰撞。电离ERS的电荷损失（电子捕获）与电荷的增益（电子损失）之间的平衡，使人们可以在轨迹计算中使用平衡的电荷状态分布，以使ER通过磁场移动。从目标到ER电荷状态分布成为平衡的点的距离对于此类计算至关重要。基于电子捕获和损失横截面以使他的能量性他的距离可以估计该距离。可用实验数据的适当近似提供了这些横截面，这些横截面应用于离子化重ER的离子电荷演化的模拟。
Highly ionized heavy evaporation residues (ERs) resulting from heavy ion (HI) fusion-evaporation reactions are knocked out from solid targets to rarefied gas of gas-filled recoil separators. In gas, these ERs undergo charge-changing collisions on their way to a detection system. An equilibrium between the loss of charge (electron capture) and the gain of charge (electron loss) for ionized ERs allows one to use equilibrated charge state distributions in trajectory calculations for ERs moving through a magnetic field. The distance from a target to the point where the ER charge state distributions become to be the equilibrated one is essential for such calculations. This distance can be estimated in simulations based on electron capture and loss cross-sections for energetic HIs. Proper approximations of available experimental data have provided these cross-sections, which were applied to the simulation of the ionic charge evolution for ionized heavy ERs.
