In-beam and decay spectroscopy of $^{251}$Md

ORAL

Abstract

Spectroscopy of transfermium nuclei is an important frontier in nuclear science. Near $Z=100$ and $N=152$, production cross sections remain high enough that such studies are feasible and provide indirect insights into the structure of superheavy nuclei. Odd-mass nuclei present a particularly compelling opportunity, as the odd particle gives direct information regarding the orbitals near the Fermi surface. We have performed in-beam and decay spectroscopy of the odd-$Z$ nucleus $^{251}$Md using the Argonne Gas Filled Analyzer coupled with Digital Gammasphere, which allows us to identify rotational bands and search for excited states built on top of high-$K$ isomers. The results of the experiment will be presented and the nuclear structure implications will be discussed.
