WebApr 21, 2024 · In 1933 the British physicists Ernest Rutherford and Mark Oliphant reported on a series of experiments in which they bombarded a thin film of the boron compound borax by a beam of protons (nuclei of hydrogen atoms) and registered the emission of high-energy alpha particles (nuclei of helium atoms). http://chemistrynoteslecture.com/Step%20by%20Step%20Notes/s12%20Radioactive%20Decay%20and%20Bombardment.pdf free cloud word artWebCockcroft, Rutherford, and Walton in 1932, shortly after they accelerated protons against a lithium target, splitting the lithium nucleus into two alpha particles, i.e., helium nuclei. This demonstrated not only the “transmutation” of elements, but also Einstein's formula E=mc 2 , since a slight loss of mass produced energetic alpha particles. free clover svg file
