Highly energetic electrons are bombarded
WebHighly energetic electrons can interact with nuclear charges and give us information about nuclear charge distribution. Neutrons interact with the nuclear potential, and provide information about the distribution of nuclear matter. Experimentally, using neutrons of energy 20 MeV or more, or electrons of 1 GeV (10 9 eV) or
