1. Neutron Diffraction While not discovered until 1932, neutrons are neutral subatomic particles possessing magnetic moments. As a result, neutrons will diffract from the layers of a crystal lattice, due to their magnetic interactions with atomic electrons. A beam of 1.0 eV neutrons strikes a crystal whose lattice planes are separated by 0.025 nm. In convenient units, the neutron mass is Mn = 940 MeV/ca. Determine the angle 6 between the incident and scattered neutron beams, for which the first...

Moderating a Neutron In a nuclear reactor, neutrons released by nuclear fission must be slowed down before they can trigger additional reactions in other nuclei. To see what sort of material is most effective in slowing (or moderating) a neutron, calculate the ratio of a neutron's final kinetic energy to its initial kinetic energy, Kf/Ki, for a head-on elastic collision with each of the following stationary target particles. (Note: The mass of a neutron is m 1.009 u, where the...

A linear particle accelerator using beta particles collides electrons with their anti-matter counterparts, positrons. The accelerated electron hits the stationary position with a velocity of 90 x 106 m/s, causing the two particles to annihilate. If two gamma photons are created as a result, calculate the energy of each of these two photons, giving your answer in MeV (mega electron volts), accurate to 1 decimal place. Take the mass of the electron to be 5.486 x 10-4 u, or 9.109...
