OK, does anyone have a ballpark figure for isotopically enriched Boron? I agree that it seems reasonable that the difficulty of separating the isotopes of Boron and Nickel would be comparable (but I don't know). The only problem using Boron as an analogy is that the raw material is almost 150 times as expensive as Nickel. That might make any direct comparison doubtful.
I've found several companies selling isotopically enriched Nickel, but none of them provide a price online. And, I'm very reluctant to start calling/writing these companies looking for such information, since I don't want to get on any more Government lists than I'm already on. As Sheldon from "The Big Bang Theory" said (paraphrasing), "It seems that if you hack in to a National Defense super-computer, and try to buy Uranium-235 on Craigslist, the NSA calls your Mother!" ________________________________ From: Daniel Rocha <danieldi...@gmail.com> To: John Milstone <vortex-l@eskimo.com> Sent: Saturday, January 21, 2012 10:40 AM Subject: Re: [Vo]:I`ll just leave this here In the specific case of Rossi, he wants to exclude nickel below 62, but purity is not a necessity, but an optimazation. So, if he roughly excludes most of what is bellow 62, that is good enough. Given that most of Ni is 58 and 60, he can determine a threshold of, say, Z=62, more or less, and roughly separates around this value. It doesn't need to bu pure and the weight difference is quite big, about the same of what is needed to separte boron 10 from 11, even so, not so precise. I think you should look for the costs of enrich boron estimate from there.
