Rutherford scattering cross-section is strongly peaked around zero degrees, and yet has nonzero values out to 180 degrees. This formula predicted the results that Geiger measured in the coming year. The scattering probability into small angles greatly exceeds the probability in to larger angles, reflecting the tiny nucleus surrounded by empty ...
Yet there was scattering, so Rutherford and his colleagues decided to investigate this scattering carefully. [57] Between 1908 and 1913, Rutherford and his colleagues performed a series of experiments in which they bombarded thin foils of metal with a beam of alpha particles. They spotted alpha particles being deflected by angles greater than 90°.
Gold foil experiments, performed by Geiger and Marsden for Rutherford which discovered the atomic nucleus Elucidation of the structure of DNA by X-ray crystallography Discovery of the antiproton at the Bevatron
Ernest Rutherford, 1st Baron Rutherford of Nelson, (30 August 1871 – 19 October 1937), was a New Zealand physicist who was a pioneering researcher in both atomic and nuclear physics. He has been described as "the father of nuclear physics", [ 7 ] and "the greatest experimentalist since Michael Faraday ". [ 8 ]

After Rutherford's discovery, subsequent research determined the atomic structure which led to Rutherford's gold foil experiment. Scientists eventually discovered that atoms have a positively charged nucleus (with an atomic number of charges) in the center, with a radius of about 1.2 × 10 −15 meters × [atomic mass number] 1 ⁄ 3 .
Rutherford (unit), a unit of radioactivity; Rutherford scattering, a phenomenon in physics which led to the development of the Rutherford model (or planetary model) of the atom and eventually to the Bohr model; Rutherford (lunar crater), a small impact crater on the Moon ' s far side; Rutherford (Martian crater), a crater on Mars
Scattering also includes the interaction of billiard balls on a table, the Rutherford scattering (or angle change) of alpha particles by gold nuclei, the Bragg scattering (or diffraction) of electrons and X-rays by a cluster of atoms, and the inelastic scattering of a fission fragment as it traverses a thin foil.
