CHAPTER 30 NUCLEAR REACTIONS AND ELEMENTARY PARTICLES 25. (a). 27. This is because boron has a high probability of absorbing neutrons, and it absorbs many neutrons that might create fission in other fuel rods. 29. (a) Q = ( m H-1 + m n m H-2 ) c 2 = (1.007 825 u + 1.008 665 u 2.014 102 u)(931.5 MeV/u) = 2.22 MeV . (b) Q = (2 m He-3 m He-4 2 m H ) c 2 = [2(3.016 029 u)
