Crystal structure, thermal expansion and melting point of americium metal

Structural study of Pu1−xAmxO2 (x=0.2; 0.5; 0.8) obtained by oxalate co-conversion

“…It is interesting to compare this result to a previous study on 239 PuO 2 [14]. In this latter case, the lattice parameter variation was expressed as (6):…”

Electron heat capacity and lattice properties of Americium

“…Information on the lattice properties of americium is scarce and contradictory [3][4][5][6][7]. Experimental data on the thermal expansion coefficient and the bulk modulus are limited in temperature and are available only for the 243 Am.…”

The crystal structure of high-pressure americium, phase III

“…At room temperature and atmospheric pressure americium metal has the double-hexagonal close-packed structure with a=3.468 and c= 11.241 A, (McWhan, Cunningham & Wallman, 1962). Application of pressure to the d.h.c.p, form results in a transformation to a face-centered cubic structure.…”
