|Abstract:||Detailed specific heat Cp measurements of delta-Pu stabilized by Am (8%–20%) were performed in the temperature range 4.5–300 K. The coefficient of the electronic specific heat delta, which reflects the quasiparticle density of states at the Fermi level EF, is smaller than originally assumed and, depending on the estimate of phonon contributions, a value between 35 and 55 mJ=molK2 can be deduced for Pu-8%Am. For higher Am concentrations, which expand the lattice, delta decreases slightly with the Am content.|
