Abstract

The reaction ${}^{208}{Pb}$ $(^{13}$ C,3n) at bombarding energies close to the Coulomb barrier has been reinvestigated in order to study low-spin states in ${}^{218}{Ra}$ and to determine the position of the $1^{-}$ and the $3^{-}$ states. Although several new levels could be identified, none of them is compatible with the deexciting of the $1^{-}$ state. This result opposes a previous work, which assigns the $1^{-}$ state to an $E_{x}$ =713 keV level.
