A Sample Holder for Raman Spectroscopic Studies of Crystals at Low Temperatures. Application: Phase Transition in Succinonitrile

Abstract
A device to improve the thermal exchange between the cold tail, in a Raman cryostat working at liquid helium temperatures, and the crystalline sample is described and a side-reference method for the temperature measurement is used. The method is then applied to the study of the phase transition in succinonitrile.
