用Ar+的457.9,476.5,496.5,514.5nm激光激发充有Ar气的Li热管,获得Van der Waal's分子LiAr在650—760nm波长范围A2П→X2∑的漫射发射光谱。讨论了产生这种发射的动力学机制。Excited by Ar+ laser lines of 457.9, 476.5,496.5, 514.5nm, the 650-760nm diffuse emission of A2Π-X2Σ lor Van der Waal's molecular LiAr has been observed in a lithium heat-pipe oven with Ar gas. The dynamics of this emission is discussed.
