In-beam γ -ray spectroscopy of low- and medium-spin levels in Po211

subject

description

The structure of the low- and medium-spin levels of the $^{211}\mathrm{Po}$ nucleus have been studied with in-beam $\ensuremath{\gamma}$-ray spectroscopy with the $^{208}\mathrm{Pb}(\ensuremath{\alpha},n)^{211}\mathrm{Po}$ fusion-evaporation reaction. The level scheme was further extended with levels of the configurations $\ensuremath{\pi}{({h}_{9/2})}_{{2}^{+}\ensuremath{-}{4}^{+}}^{2}\ensuremath{\bigotimes}\ensuremath{\nu}{g}_{9/2}$, $\ensuremath{\pi}{({h}_{9/2})}_{{8}^{+}}^{2}\ensuremath{\bigotimes}\ensuremath{\nu}{g}_{9/2}$, $\ensuremath{\pi}{({h}_{9/2})}_{{2}^{+}\ensuremath{-}{4}^{+}}^{2}\ensuremath{\bigotimes}\ensuremath{\nu}{i}_{11/2}$, $\ensuremath{\pi}{({h}_{9/2})}_{{2}^{+}\ensuremath{-}{4}^{+}}^{2}\ensuremath{\bigotimes}\ensuremath{\nu}{j}_{15/2}$, $\ensuremath{\pi}{({h}_{9/2}{f}_{7/2})}_{{8}^{+}}\ensuremath{\bigotimes}\ensuremath{\nu}{g}_{9/2}$, and $\ensuremath{\pi}{({h}_{9/2})}_{{0}^{+}}^{2}\ensuremath{\bigotimes}\ensuremath{\nu}{({g}_{9/2})}_{{0}^{+}}^{2}{({s}_{1/2})}^{\ensuremath{-}1}$. The single-particle neutron states $\ensuremath{\nu}{d}_{5/2}$ and $\ensuremath{\nu}{s}_{1/2}$ were also identified. Furthermore, a number of states feeding the low-spin structures were added.
