Neutron scattering from polarised proton domains

Abstract We report on time-resolved small-angle polarised neutron scattering from domains of polarised protons created by dynamic nuclear polarisation in frozen deuterated glycerol–water solutions containing a small amount of paramagnetic centres. In order to observe the rapid build-up of the polarisation of the protons around the paramagnetic ions and to separate it from the much slower polarisation change of the protons in the solvent, we have developed techniques that include stroboscopic SANS and NMR synchronised to cyclic microwave irradiation.
