Collision Dynamics of Rydberg Atoms and Molecules at Ultralow Energies

Flannery, M. R.

First Major Highlight: Collisional Stark Mixing at ultralow energies in Rydberg Plasmas. Atoms in high (n,l) states formed in cold Rydberg plasmas decay to the ground state in a succession of radiative transitions populating intermediate excited states. Which states are populated during cascading and with what probability can be obtained from known transition probabilities. Classical models simplify the calculation considerably, revealing the "trajectory" in nt space followed during the cascade, scaling rules and other aspects hidden within the quantal approach. Conserved Quantity (quantal analogue obscure): Quantal-Classical correspondence in radiative recombination and decay is directly demonstrated. Classical transition probabilities and radiative, recombination cross-section are in excellent agreement with quantal results. Cross section for three body collisional capture is formulated for arbitrary electron-energy distributions.First Major Highlight: Collisional Stark Mixing at ultralow energies in Rydberg Plasmas.

Three-body recombination of helium atoms at cold collision energies

Hiroya Suno

Abstract Three-body recombination (TBR) of helium atoms at cold collision energies is studied using the hyperspherical adiabatic method with different realistic interaction potentials. By considering zero angular momentum J = 0 states as well as J > 0 states, we calculate the 4He TBR rates up to about 0.1 Kelvin, and analyze the influence of modern potentials on the recombination rates. We also calculate and analyze the collision induced dissociation rates.
