In a neutron scattering experiment, a neutron scatters off the
stationary nucleus of an atom with an atomic mass of 61 amu in a 1
dimensional, elastic collision. After the collision, what
percentage of the neutron's kinetic energy was transferred to the
atom? In a second neutron absorbtion experiment, a neutron is
absorbed into the nucleus of an atom with an atomic mass of 62 amu.
After the collision, what percentage of the neutron's kinetic
energy was remains?
