The emission of beta radiation provides evidence that neutrons and protons are made up of quarks. Beta (\(\beta^-\)) decay is the release ... the electron as a beta particle.

So if the strong force binds quarks together, it becomes apparent that the weak force allows them to change flavour: for example switching a down quark to an up quark or vice versa in beta decay.

Back in 2018, a tank of the purest water, buried under kilometers of rock in Ontario, Canada, flashed as barely detectable particle slammed ... during nuclear beta decay, a type of radioactive ...

However, as the number of protons increases, more neutrons are needed to keep the nucleus stable. For example lead (lead-206) has 82 protons and has 124 neutrons. If the nucleus has too few ...

They demonstrated the new way to use high-energy particle ... a nuclear weak decay process to create the lower-neutron-number ...
