- A hydrogen atom is placed in an electric field
which is uniform in space and turns on at
then decays exponentially.
That is, for and
What is the probability that, as
hydrogen atom has made a transition to the state?
- A one dimensional harmonic oscillator is in its ground state.
It is subjected to the additional potential for a
a time interval .
Calculate the probability to make a transition to the first
excited state (in first order).
Now calculate the probability to make a transition to the second
excited state. You will need to calculate to second order.
