It is important to be aware that this experiment is not one of the ones usually cited as validating E=mc².  That was not its goal.

This experiment is not one of the ones usually cited as validating E=mc².  That was not its goal.  The generally accepted important tests of this equation are the measurements of alpha decay energies, described above.

In 1932 English physicist John Cockcroft and Irish physicist Ernest Walton performed the first artificial nuclear transmutation of nuclei, for which they were awarded the 1951 [[Nobel Prize]] in physics.<ref>[http://www.nobelprize.org/nobel_prizes/physics/laureates/1951/cockcroft-lecture.pdf John D.
