Unformatted text preview: energy K e is related to its momentum by the relativistic equation ( p e c ) 2 = K 2 e + 2 K e mc 2 , where m is the mass of an electron. See Eq. 3851. Thus, K S = ( p e c ) 2 2 M S c 2 = K 2 e + 2 K e mc 2 2 M S c 2 = (1 . 71 MeV) 2 + 2(1 . 71 MeV)(0 . 511 MeV) 2(32 u)(931 . 5 MeV / u) = 7 . 83 10 5 MeV = 78 . 3 eV where mc 2 = 0 . 511 MeV is used (see Table 383)....
