Inelastic . scattering. is a fundamental scattering process in which the kinetic energy of an incident particle is not conserved (in contrast to elastic scattering).. Principle first observed in 1946. Used for spectroscopy and imaging . Imaging techniques are a form of tomography, where slices are ’cut’ and depict. MRI utilizes signals from the body . MRI is non-ionizing, operating in radiofrequency range, unlike CT, PET, SPECT. David . J. . Keeble. Magnetic Resonance. Magnetic moments?. Magnetic. What matters is matter with moments.

Due to Pauli principle, each term can only be occupied with one electron => This yeilds the Periodic table, works regularly only for the first 18 electrons.
