The first experimental determination of a size of a nucleus was made from the results of Rutherford scattering of α particles. Distance of closest approach was found to be read into 3 ×10 -14 m for 7.7 MeV energetic α particles. This fact indicated that the size of the nucleus should be less than 3 ×10 -14 m. WebErnest Rutherford. The Discovery of Radioactivity (Ernest Rutherford) In 1899 Ernest Rutherford studied the absorption of radioactivity by thin sheets of metal foil and found two components: alpha(a) radiation, which is absorbed by a few thousandths of a centimeter of metal foil, and beta(b) radiation, which can pass through 100 times as much foil before it … dark mode in excel online
