1 Nuclear Reactions Kinematics

2

3 m d c 2 + m Li c 2 E* m Be c 2 0.0 m  c 2 + m  c 2

4 Work in units of MeV

5 Calculate the Q-value Let M-values = nuclear masses m-values = isotopic masses Conservation of electric charge  total m e values before/after are equal; therefore subtract to zero. Approximation…

6 Calculate the Q-value initial statefinal state Appproximation… mass defects

7 Calculate the Q-value Q < 0 cannot occur spontaneously - threshold T d

8 Cross section areal target density x target density (#/cm 3 ) Y is“yield”
