The observation by Ernest Rutherford and his students that refuted the plum pudding model was alpha particle deflection. This was demonstrated in Rutherford's gold foil experiment, where alpha particles were fired at a thin sheet of gold and were found to be deflected at large angles, suggesting the presence of a dense nucleus, which contradicted the plum pudding model that proposed a diffuse distribution of positive charge.
