AB - <p style="text-align: justify;">In this paper, we investigate the double ionization process of He for the shakeoff (SO) and
correlated energy-sharing (CES) channels in intense laser field based on the intense-field many body S-matrix
theory (IMST). The wavelength dependence of the ionization rate from these two channels are analyzed and
compared with each other. According to our calculation, the CES channel dominants at long wavelengths
(300-780nm), while the SO channel dominants at short wavelengths (20-200nm). The more interesting thing
occurs in the intermediate wavelength regime (200-300nm) where the contributions from the SO and CES
channels are comparable and may compete with each other.</p>
