a) How many distinct angles from the vertical axis can the orbital angular momentum vector L make for an electron with l = 7?
b)Calculate the smallest possible angle the L can make with respect to the vertical axis. (Hint: The smallest angle occurs when ml takes the maximum allowed value. Sketch L in that case and compare the vertical component, which is related to ml, to the magnitude of L, which is related to l.)
Assume that there is an isotropic hyperfine interaction between electron and nucleus (or nuclei).
Using first order perturbation theory to calculate the energies of all possible spin states. Also
calculate the possible ESR transitions between these states. Draw the energy level diagram and
ESR spectrum. Assume you have positive isotropic coupling constant.
You have electron with S=1/2 and one nucleus with I=2
An atom has completely filled inner shells and a single valence electron in an excited p state.
The filled inner shells have an orbital momentum equal to zero. A magnetic field is applied.

- Can you help me solve this problem? Imagine you have a beam of spin 1/2 particles moving in the y-direction. We can set up an inhomogeneous magnetic field to interact with the particles, separating them according to their spin component in the direction of the magnetic field, B·Sˆ. This is the Stern-Gerlach experiment (a) You set up a magnetic field in the z-direction. As the beam of particles passes through it, it splits in two equal beams: one goes up, corresponding to the spin-up particles (those whose Sˆ z eigenvalue was +ℏ 2 ), and the other goes down, corresponding to the spin-down particles. Now, you take the beam that went up and pass it through another magnetic field in the z-direction. Does the beam split? If so, what fraction of the particles go to each side?
