From exact non–Born–Oppenheimer simulations of dissociative ionization of H 2 +in an intense ( I >10 15 W/cm 2 ), ultrashort laser pulse (τ p <5 fs), we show that it is possible to measure the probability distribution |ψ v ( R )| 2 of some initial vibrational state v through the inversion of the kinetic energy spectrum of the laser‐induced Coulomb explosion. The theory of the inversion method is presented and its application to laser‐induced Coulomb explosion imaging (LCEI) of time‐dependent wave packets is demonstrated through numerical simulation. ©1999 John Wiley & Sons, Inc.
