Abstract
We study the role of singlet coupling during double ionization of Helium atoms in intense laser fields, within the framework of the recollision model. The singlet cross sections for inelastic scattering, integrated over all excitation and ionization channels, are used. Nonadiabatic corrections during tunneling of the active electron are also included.
