Experimental Evidence of the Existence of Element 85 in the Thorium Family

BESIDES the branching of the C products in the three radioactive families, Mlle. Perey and Lecoin 1,2 have shown another branching in actinium, leading to the creation of element 87. Turner 3 , considering the regularities in the distribution of isotopes, has concluded that actinium A, thorium A and...

Zusammenfassung:BESIDES the branching of the C products in the three radioactive families, Mlle. Perey and Lecoin 1,2 have shown another branching in actinium, leading to the creation of element 87. Turner 3 , considering the regularities in the distribution of isotopes, has concluded that actinium A, thorium A and radium A. should also be Î-active. Thus, the element 85 would be created. We have therefore tried to separate element 85 from some 40 mgm. of radiothorium which we had at our disposal.
