Controlling the angular momentum composition of a Rydberg electron wave packet.

Verlet, J. R. R. and Stavros, V. G. and Minns, R. S. and Fielding, H. H. (2002) 'Controlling the angular momentum composition of a Rydberg electron wave packet.', Physical review letters., 89 (26). p. 263004.


Sequences of phase-locked laser pulses have been employed to control the orbital angular momentum character of an electron wave packet, which is initially created from a superposition of s and d Rydberg series. By an intelligent choice of phase, which depends on the excitation energy and the quantum defects, we are able to selectively pump down either all or a fraction of one or other angular momentum component, and by employing multichannel quantum-defect theory we are able to analyze the quantum-state distribution in detail.
