Manipulation of differential electron yields via autoionizing wave-packet control - art. no. 033403

Ultrashort laser pulses have been used to produce nonstationary Ca 4pnl aut oionizing states via sudden isolated-core excitation of 4snl angular Rydber g wave packets. The angular distributions of the electrons ejected into the 4s epsilonl and 3d epsilonl continua are altered by varying the initial or ientation of the 4snl angular wave packet. While the observed level of cont rol is less than might be expected from an intuitive picture, it is in exce llent agreement with R-matrix quantum-defect theory calculations.
