The L018800100016 mixture was pressed into thin disks, 20 mm in L018800100017 diameter, and masses between 780 and 940 mg each, L018800100018 corresponding to a mass of pure cerium dioxide L018800100019 between 660 and 740 mg. L018800100020 DETECTOR (HPGE) HPGe detector with 60% efficiency. The L018800100021 distance between target and detector was 3 cm.
