Unformatted text preview: B between the highest and lowest n = 2 levels? Make sure that your answer has units of energy. 4. What is the numerical value of the Bohr angular frequency ab for the spinup and spindown states in a magnetic eld B of 1 Tesla, where H = g B B h S z . (1) Remember that for an electron, g 2 and B = e h/ 2 m . (b) Suppose that a perturbation is added for times t > 0, of the form H = g B B h S x (2) with B B . What is the maximum transition probability in rstorder perturbation theory, starting in the spindown state at t = 0, if B = 104 Tesla? Plot the transition probability as a function of time. 1...
