Beryllium wavefunction

(a) What is the properly antisymmetrized four-electron wavefunction $\psi(\vec{r}_1,\vec{r}_2,\vec{r}_3,\vec{r}_4)$ for the ground state of beryllium in the independent electron approximation?

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