The nonsequential ionization of one-dimensional helium atom under an intense ultrashort laser pulse is investigated with a classical ensemble theory. Through the dynamic simulation of the average Coulomb potential and the average distance between electron and nucleus, we found that high intensity and long wavelength favour the occurrence of nonsequential ionization for a given duration of pulse.
