New mass anchor points for neutron-deficient heavy nuclei from direct mass measurements of radium and actinium isotopes

M. Rosenbusch, Y. Ito, P. Schury +17

The masses of the exotic isotopes ${}^{210-214}$Ac and ${}^{210-214}$Ra have been measured with a multi-reflection time-of-flight mass spectrograph. These isotopes were obtained in fli…
