| Abstract: | The angular distributions of CO+ from the dissociation of CO22+ and CO2+ in intense femtosecond laser fields (45fs, about 5×1015 W/cm2) are studied at a laser wavelength of 800nm based on the time-of-flight mass spectra of CO+ fragment ions. The experimental results show that structural deformation occurs in the charge state of CO22+ and the CO2+ maintains linear geometrical structure. |
