How did Rutherford interpret the following observations made during his a-particle scattering experiments?
(a) Most a particles were not appreciably deflected as they passed through the gold foil.
(b) A few a particles were deflected at very large angles.
(c) What differences would you expect if beryllium foil were used instead of gold foil in a the scattering experiment?
