Two identical non-interacting particles of rest energy 0.1973 MeV are trapped in the same infinitely deep one-dimensional square well of width 0.625 µm . If the total energy of the two-particle state is 0.31568 µeV, write down the two-particle wave function in each of the following cases: 1. the particles are spinless; 2. the particles are electrons and the spin of the state iss = 0; 3. the particles are electrons and the spin of the state is s = 1; 4. When the Coulomb repulsion between the electrons is taken into account in 2 and 3 , which spin state will have the lower energy?
