Web5 mei 2012 · Although the calculation relates to nuclear scattering there will be no difficulty in applying the basic formula (2.15) to the magnetic case. We start by ignoring the spin of the neutron. This means that the state of the neutron is specified entirely by its momenturn, i.e. by its wavevector.

The images shown above were obtained at 50 kV (left) and 125 kV (right) at table top (i.e., with no scatter removal Bucky). The low kV image has superior contrast because of reduced levels of scatter. As the kV is reduced, the average photon energy is reduced; accordingly, the proportion of photoelectric interactions increases ...
