6-56. Consider the following reactions caused by tritons, nuclei of 3H, interactingwith 160 to produce the compound nucleus 19F18F + n170 + d180 + p16N + 3He3H + 160 --+ 19F*--+For each of these reactions calculate (a) the Q-value, (b) the kinematic thresh-old energy of the triton, (c) the threshold energy of the triton for the reaction,and (d) the minimum kinetic energy of the products. Summarize your calcu-lations in a table.Solution:For a binary, two-product reaction x+X --+ y+ Y we use the following resultsfrom Ch. 6.(a) The Q-value is obtained from Eq. (6.6), Q = (Mx + Mx -My -My)c2,and the atomic masses in Ap. B.(b) The kinematic and Coulombic threshold energies are obtained from Eq. (6.15)(needed when Q < 0) and from Eq. (6.19) (needed when x and X are bothcharged particles).ZxZXEc ~ 1.2 1/3Al/3
