Mimicing Charged Particle-Atom Collisions Using Half-Cycle Electromagnetic Pulses

Abstract

The research supported by this grant revealed the following important results. The development and demonstration of the Impulsive Momentum Retrieval (IMR) method for directly viewing the momentum distribution of electrons within atoms. The development and demonstration of a "single-shot delay imaging detector that allows us to view electron dynamics in quasi-real time. Measurement of atomic ionization probability in full mock-collision field, including both longitudinal and transverse field components. Demonstration and preliminary studies of free electron-ion recombination in mock collisions. Identified Stark wave packets, coherent superpositions of "stretched" atomic states as potentially useful sources of short-pulses (only a few optical cycles) of tunable THz radiation.
