In an effort to understand the excitation, ionization, and relaxation
process within helium droplets, we have studied both pure and doped
helium droplets. I will give a brief summary of our work on the
ionization dynamics of pure helium droplets followed by recent doped
droplet results on the excitation and subsequent fragmentation of SF6
within the droplets. Through a combination of time-of-flight mass
spectrometry and photoion and photoelectron imaging, we were able to
obtain new insights into the mechanisms of photoionization within the
droplet and the cooling of the hot photofragment ions produced by
dissociative photoionization of SF6.
