Homework Assignment 10 (due 4/27)
Time Dependent Perturbation Theory, Selection Rules, and
- (a) Calculate the lifetimes of the first three excited states
() of an electron in an infinite square well of width
nm. Assume only E1 transitions give significant transition
Note: The state can de-excite via two different E1
transitions, so you need to use Eq. 7.149.
(b) What are the branching ratios
of the two E1 decay modes of the state?
- Determine the selection rules for transitions triggered by
an oscillating delta function perturbation located at the center of
an infinite square well,
