No evidence of a structural phase transition in this temperature range is found, although some splitting of bands associated with the internal modes has been observed. A tentative assignment of the modes is also given. Copyright © 2006 John Wiley & Sons, Ltd. REFERENCES 1Goryainov SV, Kolesnik EN, Boldyreva EV.
