【 摘 要 】

We perform an experimental investigation on tunneling ionization of CH3X (X=I, Br, Cl) molecules in intense femtosecond laser fields (1013to 1015W/cm2). The angular distribution of the parent and fragment ions from the well aligned molecular targets has been measured. Compared with theoretical calculation, the results show some new insights into the ionization mechanism of these molecules in intense laser fields.
