Gamma Radioactivity

Gamma Radioactivity
In this example, a non-spherical nucleus 78Sr has been created by a fusion-evaporation reaction. It is highly excited when formed and this energy is in the form of rotation. It is one of the fastest rotating objects in the universe. It removes this energy and spin by emitting gamma-rays. The entire process takes pace in less tha 1 ns (0.000000001 second).

For more reading see Wikipedia's gamma decay

The typical speed of rotation (Hz) for many objects versus their size is shown in the image above.
