Abstract
THE separation of the uranium isotopes is of interest because only one of the isotopes, 235U, is believed to undergo fission when bombarded by slow neutrons. The best way to check this theory would be to change the relative particle density of 235U and to see if that has any influence on the number of fissions caused by a certain number of neutrons. If the theory proves correct, one might be able to cause a nuclear chain reaction by concentrating 235U and removing the other isotopes, which only catch neutrons without producing new ones.
