Since about 10% of natural Mg is 25Mg, if the Mg atom exists in an octahedral lattice with 6 nearest neighbors, then for any given 25Mg atom, there is a 90% chance that any given nearest neighbor will not be 25Mg. The chance that all 6 will not be 25Mg is 0.9^6 = 53%. Thus the chances that at least one of the nearest neighbors will be another 25Mg is about 47%. That means that if the neutron hopping process works, it should be able to convert about half the 25Mg in natural magnesium without any isotope enrichment being used. That means that if you want to experiment with the process, you can just use ordinary Magnesium. Not an ideal solution in the long run, but if definitely makes experimenting to determine feasibility easier. Even if my math is wrong, it won't be so far off as to make the use of ordinary Magnesium impossible for experimentation. Regards, Robin van Spaandonk http://rvanspaa.freehostia.com/project.html
