Ultracold collisions of metastable helium atoms


We report scattering lengths for the Σg , Σu and Σg adiabatic molecular potentials relevant to collisions of two metastable 2 3S helium atoms as a function of the uncertainty in these potentials. These scattering lengths are used to calculate experimentally observable scattering lengths, elastic cross sections and inelastic rates for any combination of… (More)
