K and L x-ray emission from hollow atoms produced in the interaction of slow H-like (I52+) and bare, (I53+) ions with different target materials

摘要

Through the coincidence measurement of x rays with secondary electrons, x-ray spectra, and their yields have been measured in the interaction of H-like and bare highly charged ions (I52+ and I53+) with different target materials (Be, C, Cu, and W). K x-ray yields are independent of the material, where the K vacancies are almost filled through K x-ray emission. L x-ray yields are affected by the electronic state of the targets and the interacting projectiles, because the states involved in the electron capture depend on the level structure of the projectile and the target and the possible number of electrons captured by the highly charged ions is different depending on the number of electrons in the target states (2n(2)) which are resonant transferred to the projectile states in the dynamics of below-surface neutralization and deexcitation.
