Title: Variational method for calculating the double photoionization of a helium atom
Abstract: A variational method is proposed for calculating the double photoionization of a helium atom. The principle is employed to calculate double photoionization from the ground state in the threshold region of incident photon energies, from 80 eV to 105 eV. The results of the present paper agree well with calculations previously made on the basis of the Coulomb Green's function.
