# Multiconfiguration Dirac-Hartree-Fock calculations of transition rates and lifetimes of the eight lowest excited levels of radium

@article{Biero2007MulticonfigurationDC, title={Multiconfiguration Dirac-Hartree-Fock calculations of transition rates and lifetimes of the eight lowest excited levels of radium}, author={Jacek Bieroń and Paul Indelicato and Per J{\"o}nsson}, journal={The European Physical Journal Special Topics}, year={2007}, volume={144}, pages={75-84} }

Abstract.The multiconfiguration Dirac-Hartree-Fock (MCDHF) model has been employed
to calculate the transition rates between the nine lowest levels
of radium. The dominant rates were then used to evaluate the
radiative lifetimes. The decay of the metastable 7s7p3P0 state
through 2-photon E1M1 and hyperfine induced channels is also studied.
