Error in the following:

" If we again assume that the nucleus is fixed at the center and ignore relativistic and spin effects, then the stationary states of helium are the solutions of the following equation:

E\,{\partial\psi\over\partial t}=-{\hbar^2\over2m} \left[{\partial^2\psi\over\partial x_1^2}+{\partial^2\psi\over\partial y_1^2}+{\partial^2\psi\over\partial z_1^2}+ {\partial^2\psi\over\partial x_2^2}+{\partial^2\psi\over\partial y_2^2}+{\partial^2\psi\over\partial z_2^2}\right]+ \left[-\frac{2e^2}{r_1}-\frac{2e^2}{r_2}+\frac{e^2}{r_{12}}\right]\psi. $$ "

This is neither the time-dependent Schrödinger equation for Helium nor the eigenvalue Schrödinger equation. The right hand side is correctly "H ψ" for the Helium atom, but the left hand side should be just "E ψ" in order to fit the introductory sentence.
