Formation of excited states of zinc, cadmium, and mercury atoms and ions in collisions with low-energy protons
Tsiple M. Yu. , Ovchinnikov V. L. , Shpenik O. B.
Excitation functions have been found (for the first time) for the spectral lines of zinc, cadmium, and mercury atoms and ions excited by proton impact near the threshold. Anomalously large ion cross sections have been found. An oscillatory structure found in the excitation functions of several lines indicates that the interaction of the particles is of a quasimolecule nature.
