Notes:
The variation-iteration method of Svartholm has been applied to the momentum-space Schrödinger equation for one-dimensional two-electron systems. The first and second iteration momentum-space wave functions have been evaluated in analytical forms. The momentum representation of the exact Hartree-Fock ground-state wave function is chosen as the initial function. The influence of electron correlation on the distribution of momentum-space probability density has been studied. It is shown for the one-dimensional McWeeny-Coulson problem that the numerical value of the ground-state energy of the one-dimensional two-electron atom is between the minimum energy values ε1/2 and ε1.
