Many Electron Transitions in Ion-Atom Collisions

将使用Oak进行两组实验 岭国家实验室串联货车德格拉夫加速器在 低MeV/u范围。 首先，氧离子射弹， 0.3到2 MeV/u的能量将用于轰击 分子氢和惰性气体靶。 能量和角度 将研究所得电子的分布。 在 第二组，形成Ag 4+的双激发态， 研究了Ag ~（12+）离子入射到He、H_2和Ar气体靶上的情况。 这 研究将有助于提供有关电子基本信息， 在这种碰撞中的电子相关性。

Two sets of experiments will be carried out using the Oak Ridge National Laboratory tandem Van de Graaf accelerator in the low MeV/u range. In the first, oxygen ion projectiles with energies between 0.3 and 2 MeV/u will be used to bombard molecular hydrogen and noble gas targets. The energy and angular distributions of resulting electrons will be studied. In the second set, the formation of doubly-excited states of Ag4+ and Ag12+ incident on He, H2 and Ar gas targets will be studied. This study will contribute fundamental information about electron- electron correlations in such collisions.
