Abstract :
Summary form only given. By numerical simulations we have shown that the two-photon ionization of He/sup +/ is suitable for the realization of a nonlinear optical effect in the soft x-ray region, with its high cross section, quadratic dependence on intensity, and linearity in pulse duration.
