Rotational bands in Md 249

Year: 2025

Type: article

Abstract: Rotational structures in $^{249}\mathrm{Md}$ have been observed for the first time. One set of states forms a pair of strongly coupled bands with relatively strong E2 transitions and no identifiable M1 transitions between the two signature partners. Another set of states suggests a decoupled sequence of E2 transitions. These bands are assigned as based on the $7/{2}^{\ensuremath{-}}[514]$ and on the favored signature of the $1/{2}^{\ensuremath{-}}[521]$ Nilsson level, respectively. Based on previous decay studies, these levels are thought to be the ground state and first excited state of $^{249}\mathrm{Md}$, which also agrees with theoretical predictions.
