Sommerfeld coefficient of ?-Pu determined via a low-temperature specific heat Pu-Ce study

Original language description

Low-temperature specific-heat experiments on ?-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 ?=(41.50.5)?mJ/mol?K2 and the Debye temperature?D=(103.00.5?K). As Ce is in a compressed ?-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 statesare not present at the Fermi level, low-energy excitations due to transitions of the 5f65f5 type contribute to the spectral density around the Fermi level.
