A symposium on atomic and molecular physics was held on November 18, 2005 at Goddard Space Flight Center. There were a number of talks through the day on various topics such as threshold law of ionization, scattering of electrons from atoms and molecules, muonic physics, positron physics, Rydberg states etc. The conference was attended by a number of physicists from all over the world.
Deexcitation rates, lifetimes, and branching ratios are calculated for all the J = 0, J = 1, and J = 2 bound states of the muonic molecular ion td(mu) when it serves as the nucleus of a hydrogen atom. The J = 2 binding energy (E2 = 101.59 eV) is the first reported variational result for this state. It is found that the excited J = 0 state is populated several hundred times as often as the ground state.
