Halides of the Heavier Transactinides

Earlier mention (Section 10.2.2 and Tables 10.1-10.3) of the trihalides of the transplutonium elements does not do justice to the synthetic expertise of experimentalists who have studied these compounds. Some examples of the techniques involved follow. 

The first synthesis, reported in the mid 1960s, was made difficult by the use of the shortlived Cm (h = 18.1 y) isotope, which caused significant damage to the sample through irradiation. However, by 1970 microgram quantities of Cm = 3-4 x 10 y) were

CfCls was first reported by Burns et a/., in 1973, synthesized by the ion-exchange bead route described above. As more = 351 y) became available on the /rg scale, another
