Abstract

The7Li2 21 Σ + u →X 1 Σ + g electronic transition has a bound-bound and a bound-free part due to the double minimum nature of the upper 21 Σ + u state. We have studied this transition both experimentally and by performing spectral simulations. When inner well was excited the bound-free part at 4525 Å was observed due to the collisions between Li *2 and argon. We found that when levels above the barrier are excited the bound-free emission is strongly affected by collisional relaxation of Li *2 by Li atoms. Conditions for the observation of the bound-free part are discussed.
