Lithium wavefunction

(a) What is the properly antisymmetrized three-electron wavefunction ψ(r1,r2,r3) for the ground state of Lithium in the independent electron approximation?

(b) What is the energy of the ground state in the independent electron approximation?

(c) What is the ionization energy of Li in the independent electron approximation? How does it compare to the experimental value (can be found, e.g., at www.webelements.com)?
