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?
