| Zusammenfassung: |
The relaxation data for 0.4Ca(NO3)20.6KNO3 obtained for temperatures above 100°C by ultrasound measurements and by normal as well as by stimulated Brillouin scattering experiments are reanalyzed in order to show that they all obey the time temperature superposition principle with the same Kohlrausch model as master function. The data follow a similar pattern as the neutron scattering results and the molecular dynamics curves obtained for this system. The relaxation rates characterizing the elastic modulus, the neutron scattering law, the electrical conductivity, and the shear stress follow closely a universal curve. The experimental results are shown to be compatible with the mathematical picture of the alpha-relaxation process obtained by the mode coupling theory for supercooled liquid dynamics.
