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 nonvanishing 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 ...
