The investigation of ion-exchange separation of boron isotopes 10B and 11B, on our view, is one of the important problems. Naturally occurring boron contains 19.8% 10B and 80.2% 11B. The absorption cross section of natural boron for thermal neutrons is 752 barns; for pure 10B and 11B, the corresponding values are 3837 and 0.005 barns, respectively. This means that isoto Continue Reading »
