Phys. Rev. A 70, 023406 (2004) [4 pages]Time-resolved sequential double ionization of D2 molecules in an intense few-cycle laser pulseReceived 5 April 2004; published 16 August 2004 The kinetic energy spectra of D+ ions resulting from the sequential double ionization of D2 molecules in an intense few-cycle laser field are calculated. The D2 molecule is first ionized at its equilibrium distance, followed by further ionization of D2+ at larger internuclear separations. The time evolution of the nuclear wave packet is calculated including loss from ionization by the time-dependent laser field. The calculated D+ energy spectra are compared with the recent experiment, and the time duration between the two ionization events is deduced to subfemtosecond accuracy. © 2004 The American Physical Society URL:
