The behavior of aqueous systems below critical temperature, Tc (Tc > Tg) can be described by two different scenarios. In the first one, a split of the main relaxation alpha-component occurs at Tc, and, below Tc, besides the main relaxation, there exists an additional "slow" beta-component, sometimes referred to as Johari-Goldstein relaxation. The temperature dependence of this "slow" beta component is suggested to be Arrhenius, unlike the super-Arrhenius temperature dependence of the alpha-component. In the second scenario, the additional relaxation that develops below Tc is not an independent component, but merely an "excess wing" component that follows the temperature dependence of the super-Arrhenius alpha-component. Both scenarios derive support from various experimental results. To resolve this controversy, which has been known and debated for aqueous systems ranging from confined water to hydration water on protein surfaces, we propose to carry out an NSE experiment specifically tailored to the capabilities of the IN11C. The distinct advantage of our aqueous solution system is that it has the same Tc as pure water, yet does not require confinement for supercooling below Tc.
