Correlation quantum dynamics between an electron and D+2 molecule with attosecond resolution.
Recently, Niikura et al. [Nature (London) 421, 826 (2003)] have applied the entanglement approach to exploit the correlation between the electronic and nuclear wave packets. Here, we use the time-dependent-wave-packet method to calculate the kinetic energy distribution of the D+ ion resulting from the recollision between an electron and its parent ion D+2(X2Sigma+g) within the attoseconds time scale. Our theoretical results of the D+ ion kinetic energy spectra accord well with the experimental ones, and the recollision probabilities between the electron and the D+2 molecule have been calculated.
