As part of an experiment with x-rays in 1909, Rutherford was shooting a beam of alpha particles (or alpha rays, emitted by the radioactive element radium) at a sheet of gold foil only 1/3000 of an ...

Scientists based in Manchester, not the US, made the "key breakthrough" in splitting the atom, despite Donald Trump's claims in his inaugural speech, says a lecturer at one of the city's universities.

for which he received the Nobel Prize in Physics in 1922 Rutherford’s most famous experiment involved bombarding a thin sheet of gold foil with alpha particles. The unexpected results revealed ...

Chadwick used a version of Rutherford's experiment, using a sheet of beryllium and a paraffin block instead of gold foil. He was able to prove that a proton-sized neutral particle - now known as ...
