Eight electrons are confined to a two-dimensional infinite potential well with widths L_X = L y =L. Assume that the electrons do not electrically interact with one another. Considering electron spin and degeneracies of some energy levels, what is the total energy of the eight-electron system in its ground state, as a multiple of h^2/(8mL^2 )?
