O173900100010 SAMPLE Three stacks of terbium and one of lanthanum were used.O173900100011 Thin layers of terbium oxide, Tb(4)O(7), purity 99.9% O173900100012 and lanthanum oxide, La(2)O(3), purity 99.9999% on a O173900100013 high purity aluminum backing of thickness 250 mum were O173900100014 used. After drying the samples, accurate thicknesses ofO173900100015 the sediment layer were determined by weighing each O173900100016 Al foil and subtract its weight before sedimentation. O173900100017 Each sample was covered with 10 mum Al foil to protect O173900100018 the formed layer in the stack during irradiation and O173900100019 measurements.
