Artificial transmutation

Definition

Artificial transmutation is the process by which the nucleus of an atom is changed into a different element or isotope through artificial means, such as bombarding it with particles like protons or neutrons. This process contrasts with natural transmutation, which occurs spontaneously in nature. Artificial transmutation is key in various applications, including nuclear reactions and research, and heavily relies on technologies like particle accelerators to provide the necessary energy to facilitate these nuclear changes.
