Consider a state of a 2-electron diatomic molecule AB described by the electronic
normalized wave function
Þ(1, 2) = y(1,2) [a(1) B(2) – a(2) B(1)]
where p(1, 2) is the spatial part of the electronic wave function.
(a) What must be the value of the integral (p(1, 2)|4(1,2)) so that the complete
(spatial and spin) function (1, 2) is normalized?.
(b) Is the spatial function p(1, 2) symmetric or antisymmetric with respect to the
exchange of the space coordinates of electron 1 and 2?

A one-dimensional square well of infinite depth and 1 Å width contains 3 electrons. The potential well is described by V = 0 for 0 1 Å. For a temperature of T = 0 K, the average energy of the 3 electrons is E = 12.4 cV in the approxination that one neglects the Coulomb interaction between clectrons. In the same approximation and for T = 0 K, what is the average cuergy for 4 electrons in this potential well?
