Cross-Sections of U238
Your table gives the capture cross-section for fast neutrons as 0.07barn and the fission cross-section as 0.3barn. Maybe my understanding of these values is wrong, but it seems to me that this would mean that U238 would fission with ~80% probability with fast neutrons, whereas elsewhere on Wikipedia I read 10%. The 10% number looks more plausible, because 80% would make it pretty likely that you can reach a critical mass with unmoderated U238. Is my understanding of cross-sections wrong, or are the cross-section numbers for U238 in the table wrong?
