Revisiting the hyperfine interval for the $2s2p$ ${}^3{P}_J$ state in ${}^9$Be

Yu-Shan Zhang, Wei Dang, Kai Wang +1

Using relativistic multiconfiguration Dirac-Hartree-Fock method, we calculate the hyperfine-structure properties of the $2s2p$ ${}^3{P}_J$ state in ${}^9$Be. The hyperfine-structure…
