The dynamics of exciton tunneling and trapping in condensed xenon on ultrafast time scales

We report the use of picosecond transient absorption spectroscopy to directly observe the dynamics of formation, tunneling, and subsequent cooling of the n=1, Γ(3/2) exciton in condensed xenon over a density range of 0.10 to 1.8 g/ml. At lower densities, only Xe*2 excimers are formed, which undergo...
