The impurities H-1, C-12, N-14, O-16, Na-23, Si-28, Cl-35, Cl-37, Mo-9
8 and I-127 were observed in different targets by various techniques.
It has been shown that light impurities from paraffin introduced in th
e preparation of targets by rolling and centrifugation can be reduced
by baking the target at 300-degrees-C in vacuum. The thickness variati
on over a foil was found to be within 2.8% for the 10 mm diameter targ
ets prepared by electron gun bombardment and up to 10.5% for the 12 mm
diameter targets prepared by rolling and centrifugation.
