Abstract :
Summary form only given. We present an experimental demonstration of differential process control in the time domain. In our experiment Ca Rydberg atoms (4 sns J=0) are exposed to a pair of phase-coherent laser pulses (I/sub p/=0.4 ps, /spl lambda/_=393 nm). Each laser pulse performs an "isolated core excitation" (ICE) producing a nonstationary autoionizing wavepacket at an energy just below the Ca/sup +/ 4p/sub 1/2/ ionization limit.
