Time-dependent small-angle polarised neutron scattering from
domains of polarised protons has been observed at the onset of
dynamic nuclear polarisation in a frozen solution of 98%
deuterated glycerol-water at 1
containing a small
concentration of paramagnetic centres (EHBA-
).
Simultaneous NMR measurements show that the observed scattering
arises from protons around the -ions which are
polarised to 
% in a few seconds, much faster than the
protons in the bulk.
