In the artificial transmutation of elements, Alchemists was interested to convert basic metals like iron into precious metals like gold. A number of subatomic particles was used as projectiles to hit the nuclei after accelerating these particles in cyclotron. The ejectiles were also generally some subatomic particles or in some cases, only `gamma`-radiation were emitted. These nuclear reactions are generally represented by Bethe's notation. In certain cases it is observed that artificial transmutation of a stable nucleus gives a radioisotope which disintegrates by itself like a natural radioactive element. The phenomenon is called induced radioactivity.
