*33. If a weak electric field of magnitude E is applied to an atom in its ground state (Stark effect), what happens to the energy of the atom?
(A)It is changed by an amount proportional to E.
(B)It is changed by an amount proportional to E2.
(C)It is changed by an amount proportional to E3.
(D)It is changed by an amount proportional to E4.
(E)It is not changed.
thank u in ad:)
one problem about atoms in electric field
I believe it is choice (A). Firstorder Perturbation is just the
perturbed field energy braket'ed with the 0th order (unperturbed)
wave function.
More info on firstorder pert's available (and explained with
beautiful LaTeX equations) at http://grephysics.net/disp.php?yload=pr ... =3&prob=94
