Electrons photo-emitted from a material in a UPS experiment can be viewed as free particles. A photon of wavelength 50 nm is absorbed by an electron that was in an orbital with an ionization energy IE of 12.8 eV. Use the relationship between kinetic energy and momentum (KE = p2/2m) and the quantum mechanical momentum operator p to solve for the exact unnormalized wavefunction of the electron that is photo-emitted from the orbital. Consider the +X direction only.
