Problem 6.250

A neutron collides elastically with an initially stationary deuteron. Find the fraction of the kinetic energy lost by the neutron (a) in a head-on collision; (b) in scattering at right angles.

Reveal Answer
6.250. (a) η=4mM/(m+M)2=0.89; (b) η=2m/(m+M)= 6.250 . \text { (a) } \eta=4 m M /(m+M)^{2}=0.89 ; \text { (b) } \eta=2 m /(m+M)= =2/3=2 / 3. Here mm and MM are the masses of a neutron and a deuteron.
