temperature is an intrinsic property of the ~NH) mode or is related to the temperature evolution of librational modes of the methyl group. In order to estimate the intrinsic
The results of the data analysis are shown in figure 3 and detailed in table II. From the table it is seen that the Cs salt band origins of 70H and boH move to higher energies as
In the long wavelength limit well defined acoustic modes are observed and we have shown that the slope of the TA and LA dispersion curves is isotropic. This is in good agreement
These modes could no longer be resolved in the SmB phase. - a) Schematic representation of the molecular motions for the shear mode propagating in the c* direction with a
In the present experi- ments, since most of the measurements have been done at or near the X points [I101 and [OOl], where the structure factors for two out of three

For pressures greater than 14 kbar the only successful type of pressure cell turns out to be the supported piston cylinder with A1203.. (LUCALOX, WIDALOX) pressure
