Multiconfiguration Dirac-Hartree-Fock calculations of the hyperfine structures of radium

The multiconfiguration Dirac-Hartree-Fock model has been employed to calculate the magnetic dipole and electric quadrupole hyperfine constants of the 7s6d D-3(1), 7s6d D-3(2), 7s6d D-3(3) and 7s6d D-1(2) states of Ra-223(88). This paper complements the previously published hyperfine constants for the 7s7p P-1(1) and 7s7p 3p(1,2) states, yielding the hyperfine structure data for all levels belonging to the two lowest excited-state configurations, 7s7p and 7s6d, of neutral radium.
