The task is to identify which phenomenon\u2014Bremsstrahlung radiation, Compton scattering, the photoelectric effect, or Cherenkov radiation\u2014best explains the observed change in energy distribution of gas molecules caused by the electron beam. The correct answer is Bremsstrahlung radiation, which occurs when electrons are decelerated in the electric fields of atomic nuclei, leading to the emission of radiation and energy transfer to the surrounding gas molecules."}
