Isotope Separation Methods | Atomic Heritage Foundation

· Gaseous diffusion’s principle was simple: molecules of a lighter isotope would pass through a porous barrier more readily than those of a heavier isotope The tiny weight difference between U235 and U238 meant that initial separation would be negligible Repeat the process hundreds of times in sequential "cascades," though, and the end product would be significantly
