Question

The minimum kinetic energy needed by an alpha particle to cause the nuclear reaction ^ 16 _ 7 N + ^ 4 _ 2 He ^ 1 _ 1 H + ^ 19 _ 8 O in a laboratory frame is n (in MeV). Assume that ^ 16 _ 7 N is at rest in the laboratory frame. The masses of ^ 16 _ 7 N , ^ 4 _ 2 He , ^ 1 _ 1 H and ^ 19 _ 8 O can be taken to be 16.006 u, 4.003 u, 1.008 u and 19.003 u, respectively, where 1 u = 930 MeVc^ -2 . The value of n is _____.
