Part D and E A spin-orbit interaction between a spin and an orbital motion has the form HS-o = Bs. (1) Assume that S= } for the spin and 1 = 1 for the orbital angular momentum. A. Write down the basis states without the spin-orbit interaction in terms of a direct product of spin eigenstates and orbital angular momentum eigenstates, such as 1,1 > > B. Using angular momentum summation rules, write down all possible values of j and...

4. (20 points). Consider a deuterium atom (composed of a nucleus with spin I - 1 and an electron) The electronic angular momentum is J- L S, where L is the orbital angular momentum of the electron and S is its spin. The total angular momentum of the atom is F-J+I. The eigenvalues of J2 and F2 are j(j + 1)n° and f(f+1)ћ, respectively a. What are the possible values of the quantum numbers j and f for a deuterium...
9. An electron moving with non-relativistic velocity v in an electric field E experiences a magnetic fieldB given by: v x (-V(r)) v x E B=- where (r) is the electric potential. This magnetic field interacts with the magnetic moment u of the electron given by -S, =n me where S is the electron spin. Assuming non-relativistic mechanics, show that the Hamiltonian representing this effect (spin-orbit coupling) for a spherically-symmetric electric potential is: 1 dφ(r) S.L ΔΗ [6] r dr...

why total orbitals are 6 ?? and please answer the number of orbitals of self test 9c.3 No Brief illustration 90.3 Spin-orbit coupiny The unpaired electron in the ground state of an alkali metal atom has l=0, so j=1. Because the orbital angular momen- tum is zero in this state, the spin-orbit coupling energy is zero (as is confirmed by settingj=s and 1=0 in eqn 9C.4). When the electron is excited to an orbital with I=1, it has orbital angular...
