✦ Synopsis

Recent high-pressure experiments have revealed that Y, La, Ce, Pr, Am, Cf, and Cf0.6Bk0. 4 display a distorted fcc structure beyond the well-known sequence hcp-Sm type-dhcp-fcc. Six structures have been so far proposed for this phase. Here, we add two more distorted fcc structures. However, the analysis of diffraction data of Pr III, Nd III, Ce and Tb seems to suggest that these structures are merely different indexing schemes at present.
