Abstract
International audience; γ rays following the EC/β+ and α decay of the $N = 126, ^{213}$Fr nucleus have been observed at the CERN isotope separator on-line (ISOLDE) facility with the help of γ-ray and conversion-electron spectroscopy. These γ rays establish several hitherto unknown excited states in $^{213}$Rn. Also, five new α-decay branches from the $^{213}$Fr ground state have been discovered. Shell model calculations have been performed to understand the newly observed states in $^{213}$Fr.
