- Abstract
- We studied the collective excitations in an aqueous solution of lithium chloride over the
temperature range of 270-205 K using neutron and x-ray Brillouin scattering. Both neutron and
x-ray experiments revealed the presence of low- and high-frequency excitations, similar to the
low- and high-frequency excitations in pure water. These two excitations were detectable
through the entire temperature range of the experiment, at all probed values of the scattering
momentum transfer (0.2 °A
-1
< Q < 1.8 °A
-1). A wider temperature range was investigated
using elastic intensity neutron and x-ray scans. Clear evidence of the crossover in the dynamics
of the water molecules in the solution was observed in the single-particle relaxational dynamics
on the ?eV (nanosecond) time scale, but not in the collective dynamics on the meV
(picosecond) time scale. (literal)
