keV离子角分布的相关性和透射沟道几何中的超导电子激发
On the correlation of angular distributions of keV ions and trajectory-dependent electronic excitations in transmission channelling geometry
摘要：
我们使用的能量歧视千电子伏离子传输通过一个薄的，单晶硅膜相关的特定角分布模式中形成的沟道几何形状与磁阻相关的电子能量损失。因此，传输离子的整体能量和强度分布可以被分解成在一侧沿相当直的轨迹行进的轴向通道射弹和在另一侧主要经历阻塞的去通道射弹。进一步用两种不同的蒙特卡罗程序模拟了透射离子的角分布。
英文摘要：
We use energy discrimination of keV ions transmitted through a thin, single-crystalline silicon membrane to correlate specific angular distribution patterns formed in channelling geometry with trajectory-dependent electronic energy loss. The integral energy and intensity distribution of transmitted ions can thus be dissected into on one side axially channelled projectiles travelling along rather straight trajectories and on the other side dechannelled projectiles predominantly experiencing blocking. Angular distributions of transmitted ions are further simulated with two different Monte-Carlo codes.
