The energy levels of the one-dimensional harmonic oscillator are given by E_n = (n + 1/2)ћω with n = 0, 1, 2, . . . . Suppose two spin-1/2 fermions are trapped in a one-dimensional oscillator potential. What are the energies and degeneracies of the first three energy states of this system? (Remember that the degeneracy is the number of independent states with the same energy.)
