Rutherford's Experiment:

Chadwick's Experiment. In Chadwick's experiment, he shot alpha particles at beryllium foil and found that in doing so, a beam (A) of particles was emitted from the beryllium. When passed through a magnetic field, the particles were not deflected at all. He aimed to find out what these "beryllium rays" were made of.

Rutherford model | Definition & Facts | Britannica

In 1909 Rutherford disproved Sir J.J. Thomson's model of the atom as a uniformly distributed substance. Because only very few of the alpha particles in his beam were scattered by large angles after striking the gold foil while most passed completely through, Rutherford knew that the gold atom's mass must be concentrated in a tiny dense nucleus.

Because it is unusually ductile, gold can be made into a foil that is only 0.00004 cm thick. When this foil was bombarded with -particles, Geigerfound that the scattering was small, on the order of one degree. These results were consistent with Rutherford's expectations. He knew that the -particle had a considerable mass and moved quite rapidly.
