ANISOTROPIC FRAGMENTATION OF NITRIC OXIDE IN INTENSE LASER FIELDS STUDIED BY SINGLE PATHWAY MASS RESOLVED MOMENTUM IMAGING Atsushi Iwamae, Akiyoshi Hishikawa and Kaoru Yamanouchi Department of Chemistry, School of Science, The University of Tokyo, Japan Japan Science and Technology Corporation, Japan The spatial momentum vector distribution of fragment ions produced through t he Coulomb explosion of NO in an intense laser field (1.4 PW/cm2), NO(p+q)+ -> Np+ + Oq+ (p, q = 1~3), was studied by the mass-resolved momentum imagin g (MRMI) technique. The MRMI maps for a single pathway (p, q) were extracted from the experimental MRMI maps on the basis of the momentum matching of the Np+ and Oq+ ion pair. The angular distributions of the fragment ions derived from the SP-MRMI maps were found to be described well by a molecular alignme nt theory.
