dc.description.abstractLow-temperature specific-heat experiments on d-Pu stabilized by Ce give the value of the Sommerfeld coefficient ¿ in the close vicinity of 40 mJ/mol K2. The most precise data set for Pu-6.1 at. % Ce yields ¿ =(41.5±0.5) mJ/mol K2 and the Debye temperature TD=(103.0±0.5 K). As Ce is in a compressed a-Ce state, major contribution to the ¿ value comes from the Pu states. Theoretical calculations suggest that the 5f6 admixture in the 5f5 ground state is responsible for the high-¿ value. Although the 5f states are not present at the Fermi level, low-energy excitations due to transitions of the 5f6¿5f5 type contribute to the spectral density around the Fermi level.en_GB
