摘要：
The angular distributions of CO+ from the dissociation of CO22+ and CO2+ in intense femtosecond laser fields (45 fs, about 5 x 10(15) W/cm(2)) are studied at a laser wavelength of 800 nm 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.
