An off-resonance radiation pulse that causes spin excitation creates a shift named for Siegert and this man.  
An off-resonance radiation pulse that causes spin excitation creates a shift named for Siegert and this man.  A function that describes the temperature-dependence of the resistivity in a metal is named for Gruneisen and this scientist. The energy emitted due to ionization loss is described by an equation named for Bethe and this man, who also used a microscopic theory to develop the first dispersion relation for magnon spin waves. This man collaborated with Alvarez to measure the magnetic dipole moment of the neutron using an improvement on a technique developed by Rabi. This man lends his name to a rotating boundary between two magnetic domains known as his namesake wall.  For 10 points, name this scientist who, with Edward Purcell, developed NMR.
