Abstract

Raman scattering experiments on single-crystal UBe//1//3 have been performed at temperatures 2 less than equivalent to T less than equivalent to 300 K. We observe Raman-active optical phonons consistent, in number and symmetry, with those allowed by the space and site group symmetries previously determined for UBe//1//3 (space group O//h**6-Fm3c). Certain phonon modes are seen to have strongly anomalous behaviour with decreasing temperature. We have, in addition, observed inelastic scattering from magnetic excitations, which we identify as spin fluctuations. The temperature dependence of these excitations is discussed.
