Linearly polarized light of angular frequency w is incident on a one-electron ?atom? whose wave function can be approximated by the ground state of a three-dimensional isotropic harmonic oscillator of angular frequency w₀. Show that the differential cross section for the ejection of a photoelectron is given by provided the ejected electron of momentum hk_f can be regarded as being in a plane-wave state. (The coordinate system used is shown in figure).
