Systematic investigation of diverse Pu compounds reveals that the 5f occupancy plays a key role. If the 5f states are populated by more than approximately 5.3 electrons, the Pu magnetism vanishes. For comparison with valence-band photoemission spectra, the Hubbard I method was used. It shows consistently higher 5f5 final-state multiplet originating from the 5f6 admixture in the ground state for those compounds which are nonmagnetic. The 5f occupancy can reach 5.6-5.7 for Pu monochalcogenides. Workplace Institute of Physics Contact Kristina Potocká, potocka@fzu.cz, Tel.: 220 318 579 Year of Publishing 2010
