Unformatted text preview: Corrections to Prob. Set 8 1. In Problem 3, the calculation is difficult if you do not assume that ka is small compared to unity (here k is the wave vector of the final, freeelectron state and a is the linear dimension of the atomic 1s state). Therefore, you should make this assumption in your calculation, and just calculate the ionization rate to lowest non-vanishing power in ka. 2. In Problem 4, instead of cn (t) in eq. (1), I should have written cn (t) exp(-iEn t/ ), h where En is an eigenvalue of the unperturbed Hamiltonian H0 , i. e., H0 |n = En |n . 1 ...
