The observation by Ernest Rutherford and his students that refuted the plum pudding model was "alpha particle deflection." This was based on their famous gold foil experiment, where they observed that some alpha particles were deflected at large angles, indicating the presence of a small, dense nucleus, contrary to the evenly distributed positive charge proposed by the plum pudding model.
