Neutrino oscillation is weird, but it may be weird in a useful way, because it might allow physicists to probe certain ...

After emitting an alpha or beta particle, the nucleus will often still be ‘excited’ and will need to lose energy. It does this by emitting a high energy electromagnetic wave called a gamma ray. Gamma ...

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 neutrons, ...
