摘要
The coincidence imaging technique is applied to direct determination of the momentum vectors of all the fragment ions produced through every event of the Coulomb explosion of a single molecular ion, CS22+ (z = 2-4) formed in intense laser of CS23+ just fields (similar to 60 fs, 0.36 x 10(15) W/cm(2)). The molecular structure I before the Coulomb explosion, CS23+ --> S+ + C+ + S+, is reconstructed from the measured momentum vectors of the fragment ions. The mean C-S bond length of <r > = 2.5 Angstrom and the azimuthally averaged S-C-S bond angle, < gamma > = 145 degrees, thus determined indicate that structural deformation occurs to a large extent in the intense laser fields.
