Figures

Image of FIG. 1.
FIG. 1.

The KER distributions of the two-body Coulomb explosion, C2 → H+ + C2 for the measurements with 120 fs laser pulses at the event rate of (a) 0.14 event/shot and (b) 0.46 event/shot. Black circle: the KER distributions obtained from the momentum pairs which fulfill the momentum conservation law. Red line: the KER distributions of the false coincidences estimated through the present method. Blue square: the KER distributions obtained through the subtractions of the red lines from the black circles.

FIG. 2.

The angular distributions of the two-body Coulomb explosion processes. Black circles: C2 + C2 . Red squares: C2 + C2 . Blue triangles: C2 → H+ + C2 . The angle θ is the angle between the laser polarization vector and the momentum vector of the fragment ions. Vertical errors are comparable or smaller than the size of corresponding markers. (Inset) The angular distributions drawn as polar plots in degrees.
