摘要: Abstract The oxides of berkelium were prepared by loading 1 μg carefully purified 249Bk onto single beads ion exchange resin and calcining the to remove organic material yield oxides. Air firing gave BkO2, which had a face-centered cubic lattice with a3= 5·334±0·005 A . Hydrogen reduction BkO2 body-centered Bk2O3 = 10·880 ± 0·005
