Different neutron states could explain why different experiments produce different figures for how long neutrons survive ...

A method to take snapshots of exploding nuclei could hold clues about the fundamental properties of gold, uranium and other ...

^{4}\textrm{He}\) When a radioactive atom emits an alpha particle the mass number decreases by four and the atomic number drops by two. Here is the equation for the alpha decay of radon-219 into ...

students will be familiar with the parts of the atom and will have learned that radioactivity is a result of nuclear decay. Next, students will complete the virtual lab: The Effects of Distance and ...

harness the energy released by nuclear isotopes when they decay, said Betavolt in a press release. This decaying radioactive energy is converted into electrical power using semiconductor converters.

As long as they are part of a stable atomic nucleus, they can stay there for arbitrary periods of time. However, the situation is different for free neutrons: They decay -- after about fifteen ...
