title: Interaction potentials of uranium cations with rare gases (RG) and transport of U+ in RG (RG = He, Ne, Ar, Kr, and Xe).
abstract: We present accurate interaction potentials for uranium cations interacting with the rare gases (RG = He-Rn), using effective core potentials that include a description of the 5f electrons in the case of uranium, and justify this approximation in some detail. From these interaction potentials, spectroscopic parameters are derived for the U(+)-RG complexes. We also employ the potentials to calculate transport coefficients for U(+) moving through a bath of each RG. In the case of U(+) in He, we are able to compare with previous experimentally determined mobility values, and we make some minor corrections to the previously reported data; this revised data is presented.
