This study in is principle possible by measuring inelastic neutron scattering cross
- sections as a function of both energy ... The neutron cross - section is actually
given by the Fourier transform of the spin - spin correlation function Sap ( xt ) = ( o

Thus considering a surface defined by the neutron scattering , Im Xa ( w ) , the
neutrons at fixed angle cut a cross - section of this surface along one of the above
curves . The scattering cross - section as a function of energy loss at fixed neut O
