collisional decoherence; Rydberg wavepackets
Collisional interactions represent a major source of decoherence for a gas of Rydberg atoms. We investigate the irreversible dephasing of coherently excited Rydberg wavepackets due to decoherence in collisions with ambient rare gas atoms. We show that the rate of decoherence provides a sensitive tool for measuring quasi-clastic electron-atom (or molecule) collisions at energies extending down to micro electron volts, We present proof of principle calculations for n similar or equal to 388 potassium Rydberg atoms in an ambient gas of xenon atoms, (c) 2005 Published by Elsevier B.V.
