Yeah, Bonzi, it sounds like you've got a pretty good handle on what they'd be up against if they tried it.

Actually, I intended this as an illustration of a not too difficult problem (if you have all the data you need) . But, as Rob says in another post, the problem seems to be exactly in not having necessary data (e.g. published cross sections, fluorescence yields and shell energies, in my example). Hey, I am starting to exibit traces of nostalgia for my physicist days!?

Anyway, that graph looked like a nice idea....

(BTW, I see that Paul or wwwthreads authors have abandoned spelling checker's silly suggestions. Pitty, they were funny.)

Cheers!
