abstract = {The relaxational dynamics in glass-forming glycerol and
glycerol mixed with LiCl is investigated using different
neutron scattering techniques. The performed neutron spin
echo experiments, which extend up to relatively long
relaxation time scales of the order of 10ns, should allow
for the detection of contributions from the so-called excess
wing. This phenomenon, whose microscopic origin is
controversially discussed, arises in a variety of glass
formers and, until now, was almost exclusively investigated
by dielectric spectroscopy and light scattering. Here we
show that the relaxational process causing the excess wing
can also be detected by neutron scattering, which directly
couples to density fluctuations},
