A neutron hits an atomic nucleus in a head-on collision and comes to a complete stop. It loses all..

A neutron hits an minute core in a head-on conflict and comes to a total plug. It risks all of its kinetic ghost in the rule. If an selfselfsame neutron then scatters off of the selfselfsame minute core at an angle of 60° in the COM scheme, what lot of its kinetic ghost does it risk in a single ductile conflict?
