Paper Abstract

Collisional transitions resulting from the interaction between H -like Li+2 ions and low energy electrons in recombining laser-produced plasma (LPP) of lithium were inve0i-gated experimentally and theoretically. In the experiment relative intensities of Li+4. lines, located in the VUV region,were measured. The lines correspond to the transitions 22 -rid, n412. The excited levels are populated via three body recombination process twoselectrons plus an ion), which is very intensive in expanding' overcooled IJIT having considerable density and average ion charge but low temperature (ne~I0I5) cm-3}, Te~I eV at 2cm from the target). The population distribution for highly excited levels obtained experimentally is compared with a theoretical picture, calculated using a new approach to the three Coulomb centers problem based on consideration of quasistationary and virtual states.
