Electron Vacancy Production in Near-symmetric Collisions of 100 MeV Copper Ions

Abstract

With a high-resolution Si(Li) X-ray detector, characteristic K X rays have been detected with targets of Cr, Fe, Cu, Ge and Se ombarded by 100 MeV Cu ions, equilibrated by passing through carbon. Cross sections for X-ray production, target-to-projectile vacancy-sharing ratios and K, to K, ratios were measured and compared with predictions of molecular-coupling theories. The results show little greement with existing models based on rotational coupling in molecular-orbital states.
