Homework Statement
A Stark effect experiment is performed on the rubidium D1 line ##(5p \ {}^2P_{1/2} →
5s \ {}^2S_{1/2})## at 780.023 nm. Given that the polarizabilities of the ##5p \ {}^2P_{1/2}## and ##5s \ {}^2S_{1/2}## levels are ##6.86 × 10^{−16}## and ##2.78 × 10^{−16} cm−1 m^2 V^{−2}## , respectively, deduce the field strength that would have to be applied to shift the wavelength by 0.001 nm, stating
whether the wavelength shift would be positive or negative.
Homework Equations
The Attempt at a Solution
So i know that basically; ##\vec{p}=\alpha \vec{E}##
and so ##\Delta \epsilon=-\frac{1}{2}\alpha E^2## by integrating from ##E=0## to ##E=E##.
I know that both levels shift by an amount proportional to their polarization but, I am just completely stuck on how to go about solving it.
I drew a diagram and understand the process i think, just when i go about solving it I end up with stupid answers.
