Just answer (f)
Just answer (f)
13.17 Consider two indistinguishable, noninteracting spin-1/2 fermions in a one-dimensional infinite square well potential of length L. a) What is the ground-state energy of the two-particle system? b) What is the ground-state wave function? c) What is the first excited state energy of the two-particle system? d) What are the wave functions of the first excited state? e) What is the degeneracy of the first excited state? f) Discuss qualitatively how the excited-state energies change if we consider the particles to be interacting through the Coulomb potential.
