Film Mediated Interactions Alter Correlations and Spectral Shifts of Hydrogen Adsorbed on Helium Films

摘要: The work presented in this chapter gives a mechanism which is expected to reduce, potentially dramatically, the collision probability of two spin-polarized hydrogen atoms adsorbed on helium film. This was motivated by experiments Ahokas et al. observed anomalously small collisional shifts. Refs. [1, 2] revealed that symmetry missed original likely responsible for reduction, however our still relevant affects other observable properties: atomic recombination rates, spectral lines, and suggests cloud will collapse at sufficiently low temperatures.
