Measuring Nuclear Wave Functions by Laser Coulomb Explosion Imaging

摘要

From exact non-Born-Oppenheimer simulations of dissociative ionization of H_2~+ in an intense (I > 10~(15) W/cm~2), ultrashort laser pulse (#tau#_p < 5 fs), we show that it is possible to measure the probability distribution |#psi#_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.
