I want to know the answer to the following question:
What enrichment process was used by the Manhattan Project?
All the background I'm provided with is that "The gas centrifuge process, where gaseous uranium hexafluoride (UF_6) is separated by the difference in molecular weight between 235UF6 and 238UF6 using high-speed centrifuges, is the cheapest and leading enrichment process.". Is that enough to answer the question?
