Abstract

Using a triple axis spectrometer we have measured the quasi-elastic scattering from liquid gallium droplets down to near the lowest temperature T L = 150 K at which the liquid remains in the supercooled state. Special reference was given to values of the wave-vector Q0 = 2.50 Å-1 and Q00 = 3.12 Å-1 corresponding respectively to the mean peak and the shoulder in the structure factor S(Q). At Q0 the full width at half height of the Lorentzian profile fitting the quasi-elastic peak is found to vary linearly with temperature below 333 K, with a rate equal to 0.001 6 ± 0.000 2 THz. K-1 approaching a zero value at T = 157 ± 10 K which we associate with the metastability limit of the liquid state.
