The Transmutation of Elements


Thomassen, Lars (1928) The Transmutation of Elements. Dissertation (Ph.D.), California Institute of Technology. doi:10.7907/MRCC-NA33.


The first scientifically established transmutation of a chemical element, performed by artificial means, is due to Rutherford who showed in 1919 that it is possible to disintegrate nitrogen atoms by bombarding them with high velocity [alpha]-particles. These projectiles form a very powerful energy agent, and when they hit a nitrogen nucleus under suitable conditions, they knock out a hydrogen nucleus. Later investigations have shown that a number of elements can be disintegrated by this procedure.
