✦ Synopsis

Compounds of the fom Ba&,with x= 3 and 6 resulting from the reaction of Cm with Ba have been prepared and characterized by photoemission. For x= 3 the t,, band derived from the LUMO of Cs,, is filled, resulting in an electronic structure similar to that of&&, Upon further exposure to Ba, the t,, band becomes occupied, but the system remains metallic at the largest Ba concentration that could be achieved. The superconductivity is associated with the t,, band.
