High-spin spectroscopy and shell-model interpretation of the N < 126 radium isotopes ${}^{212}$Ra and ${}^{213}$Ra

T. Palazzo, G. J. Lane, A. E. Stuchbery +8

The level structures of ${}^{212}$Ra and ${}^{213}$Ra have been established via time-correlated $\gamma$-ray spectroscopy following the ${}^{204}$Pb(${}^{12}$C,4$n$)${}^{212}$Ra and ${}^{204}$Pb($^…
