Nonrelativistic Ab Initio Calculation of the Interaction Potentials Between Metastable Ne Atoms

April 1, 2000

Author(s)

Svetlana A. Kotochigova, Eite Tiesinga, I Tupitsyn

We compute non-relativistic ab initio electronic potential surfaces for two-metastable 2p 53s neon atoms using a multiconfiguration all-electron valence-bond method. Spectroscopic constants and long-range C 6 dispersion coefficients are presented for 3,5ς

Manipulation of Feshbach Resonances in Ultracold Atomic Collisions Using Time-Dependent Magnetic Fields

February 1, 2000

Author(s)

F H. Mies, Eite Tiesinga, Paul S. Julienne

We have calculated the time-dependent dynamics of two ultracold Na atoms in an atom trap where a time-dependent magnetic field B(t) moves a Feshbach resonance state across the energy threshold for a binary collision. Our coupled channels scattering
