AFOSR Grant: F49620-99-1-0277: Activities, Findings, Publications and Products
Abstract
A detailed account of the progress achieved under the present AFOSR grant is provided, with full documentation of the results and papers published. The Collision Dynamics of Stretched Atoms was investigated within the processes of: (a) electron- ion recombination at ultralow temperatures T ^ 5mK, and (b) three body recombination between positrons and antiprotons at 4K to form antihydrogen. The long outstanding problem (^ 40 years) of collisional Stark Mixing in Rydberg Atoms was solved exactly in both classical and quanta formulations of the problem. Here analytical expressions are provided for the probabilities for the full array n l-n 1' of transitions in a Rydberg atom in state n l, induced by the time-dependent (dipole) electric field generated by adiabatic collisions with an ion at ultralow energies. In addition, the classical form factor for n l-n' 1' transitions was defined. This permitted a detailed investigation of classical / quantal transition probabilities arising from any external sudden perturbation (whether due to collisions with particles or to pulses of electromagnetic radiation) on Rydberg systems.
