Identification of the Atomic Number of Nobelium by an X-Ray Technique

Abstract

A daughter x-ray identification scheme, in the original spirit of Moseley, has been applied to the identification of element 102, nobelium. The identification scheme is based on the coincident observation of $K$-series x rays from the daughter element, fermium in this case, with the $\alpha$ particle from the decay of the parent element, nobelium. We believe the technique provides an unequivocal identification of atomic number for the transfermium elements.
