We have measured the angular distribution of electrons reflected from Cu(001) having excited: i) an interband transition, ii) a plasmon, and iii) a core electron. We have found that the angular patterns in cases i) and ii) are similar to the angular pattern of elastically reflected electrons; in particular, the inelastic electrons are reflected along the Bragg directions at low energies and along the main crystallographic axes at intermediate energies. The angular pattern of the electrons reflected having created a Cu‐3p vacancy is also concentrated along the crystallographic axes at intermediate energies but at low energies the maxima of intensity are not along the Bragg directions.
