transmutation, neutrons

When an element undergoes nuclear transmutation the result is a completely different element or isotope. All transmutation occurs through decay or nuclear reaction.

In nuclear science, transmutation is where one chemical element or isotope is converted into another. It occurs when materials decay, or it can be caused by nuclear reaction.

Transmutation is a nuclear reaction.
Transmutation by chemical reactions is only a phantasy of the Middle Ages.
