A radioactive isotope's nucleus is unstable and spontaneously decays, giving off radiation and changing into a different isotope. The rate at which nuclei decay is constant. Half-life describes ...

The questions in this quiz are suitable for GCSE physics students studying stable nuclei ... equations. If you struggled with the quiz, don't panic - we've got you! You can revise radioactive ...

and which is also responsible for holding atoms together), the weak nuclear force (which acts inside atomic nuclei, and is responsible for a certain kind of radioactive decay), and the strong ...

The technique of neutron activation analysis is based on the measurement of radiation released by the decay of radioactive nuclei formed by neutron irradiation of the material. The most suitable ...

Some natural elements are unstable. Therefore, their nuclei disintegrate or decay, thus releasing energy in the form of radiation. This physical phenomenon is called radioactivity and the radioactive ...

Particle-accelerator study focuses on the r-process thought to be responsible for forming elements heavier than iron ...

The strong nuclear force holds the kernels of matter, atomic nuclei, together ... place where it is most obviously at work: in radioactive beta decay. In the most common form of this decay ...

However, when particles transform or decay into other particles, for example as occurs when an atomic nucleus undergoes radioactive decay, CP violation causes a crack in this mirror-like symmetry.

Studies that explore how the denser sections of atoms, known as atomic nuclei, interact with neutrons ... unstable nucleus that undergo the radioactive decay process), the researchers developed ...
