David, I don't think your test will work.
The 782 keV figure assumes no additional energy is lost in producing neutrons. Second, you have to assume you can get the process to work in Be. The cooling effect (albeit totally infinitesimal) should occur if you use a stream of super-cooled neutrons. But, why couldn't you just look for 9Be to 10Be conversion directly which should happen quickly?
