| 英文摘要 | in intense femtosecond laser fields, molecules could be tunnel ionized from multiple valence orbitals, which produces molecular ions in different electronic states. in this article, we have used a reaction microscope to study double ionization of nitrogen by intense femtosecond laser pulses. it is found that some doubly charged molecular ions n(2)(2+) are metastable while others dissociate through charge symmetric dissociation (n(2)(2+) -> n(+) + n(+)) or charge asymmetric dissociation (n(2)(2+) -> n(2+) + n). the kinetic energy releases and angular distributions of atomic ions are measured for the dissociation channels. with the aid of the casscf and mrci calculations, the electronic states are identified and the contributions of the valence orbitals are discussed for these dissociated molecular dications. |
