Tantalising news about element 117
117Notes from the 31st meeting of PAC for Nuclear Physics seems to suggest that a claim for element 117 (at the base of the halogen column) may come in the coming weeks and months. It’s not very clear which isotopes may have been formed so watch this space.
IV. Experiments on the synthesis of element 117
The PAC heard with great interest the report on the results of the experiment dedicated to the synthesis of element 117 in the 48Ca + 249Bk reaction.
