WebNov 19, 2024 · Size of Nucleus. 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.
