We describe a set of experiments that investigate diffusion of barium 6 s5d DJ metastable level and 6s S0 ground-state atoms through the noble gases: He, Ne, Ar, Kr, and Xe. The barium metastable levels were populated through optical pumping of the 6 s S0→6s6p P 1 intercombination transition with a pulsed laser, followed by spontaneous or stimulated emission into the 6 s5d D1,2 levels. Collisional mixing then distributed population throughout the 6 s5d DJ levels. A weak narrow-band cw laser was… CONTINUE READING
