$Ab$ $initio$ calculation of hyperfine-structure properties to extract nuclear magnetic octupole moments of ${}^{69}$Ga and ${}^{71}$Ga

Fei-Chen Li, Yong-Bo Tang

We calculate the hyperfine-structure properties of the low-lying states in ${}^{69}$Ga and ${}^{71}$Ga using the relativistic coupled-cluster method at the singles and doubles (RCCSD)…
