Decay spectroscopy of <sup>251</sup>Md

ORAL

Abstract

Studies of transfermium nuclei, which are amenable to detailed spectroscopy, help to constrain models which predict the structure of superheavy nuclei. We have performed a decay spectroscopy experiment focused on the odd-Z nucleus 251Md, populated via the 205Tl(48Ca,2n) reaction at the ATLAS facility of Argonne National Laboratory. Fusion-evaporation residues were separated from the beam and identified at the focal plane of the Argonne Gas Filled Analyzer (AGFA). The X-Array was placed surrounding the AGFA focal plane such that γ rays emitted from a high-K isomer could be observed populating rotational bands. The results of the experiment will be presented and the nuclear structure implications will be discussed.
