- A hydrogen atom is in a uniform electric field in the
direction which turns on abruptly at and decays exponentially as a
function of time,
.
The atom is initially in its ground state.
Find the probability for the atom to have made a transition to the
state as
.
You need not evaluate the radial part of the integral.
What components of orbital angular momentum are allowed in the
states generated by this transition?
