The observation by Ernest Rutherford and his students that refuted the plum pudding model was alpha particle deflection. In their gold foil experiment, they found that some alpha particles were deflected at large angles, leading them to conclude that the atom has a small, dense nucleus, contrary to the uniform distribution of positive charge suggested by the plum pudding model.

(1 point)
alpha particle deflection
