Abstract
The volume dependence of the Raman frequencies in - has been measured yielding the following values of the Grüneisen parameter at 8°K: 2.09±0.12, 1.74±0.10, and 1.70±0.10, where refers to the , low-frequency , and high-frequency modes, respectively. These values are insensitive to temperature within experimental errors. The broad feature between 70 and 100 is identified as a two-libron band.
