Unformatted text preview: t g τ in each of the four n = 2 states: { n, l, m } = { 2 , 1 , ± 1 } , { 2 , 1 , } , { 2 , , } . 3. The ground state of a hydrogen atom is subjected to a timedependent potential as follows: V ( x , t ) = V cos( kzωt ). (2) Using timedependent perturbation theory, obtain an expression for the transition rate at which the electron is emitted with momentum p . Show, in particular, the angular distribution of the ejected electron in terms of θ and φ deFned with respect to the zaxis....
