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.
\[ 6.250 . \text { (a) } \eta=4 m M /(m+M)^{2}=0.89 ; \text { (b) } \eta=2 m /(m+M)= \] \(=2 / 3\). Here \(m\) and \(M\) are the masses of a neutron and a deuteron.
