Consider a helium atom where both electrons are replaced by identical charged particles of spin-1. Ignoring the motion of the nucleus, the Hamiltonian is [see attachment 1] Construct an energy level diagram ( qualitatively ) for this "atom", when both particles are in the n=1 state, and...

Two identical spin-1/2 fermions are placed in the one-dimensional harmonic potential V(x)=(1/2) m w^2 x^2, where m is the mass of the fermion and w its angular frequency. (1) Find the energies of the ground and first excited states of this two-fermion system. Express the...
