Problem 6.278

How much, in per cent, does the threshold energy of gamma quantum exceed the binding energy of a deuteron \(\left(E_{b}=2.2 \mathrm{MeV}\right)\) in the reaction \(\gamma+H^{2} \rightarrow n+p ?\)

Reveal Answer
 By Eb/2mc2=0.06%, where m is the mass of a deuteron. \text { By } E_{b} / 2 m c^{2}=0.06 \%, \text { where } m \text { is the mass of a deuteron. }
