Question:
For a closed-shell atom, an anti-symmetric wave function can be represented by a single Slater determinant. For an open-shell atom, more than one determinant is needed. Show that the wave function for the MS = 0 triplet state of He 1s12s1 is a linear combination of two of the Slater determinants of Example Problem 21.2. Which of the two are needed and what is the linear combination?
