Abstract

Laser resonant photoionization spectroscopy was used to study the hyperfine structure of the optical $Mathematical equation: $3d^{8}4s^{2} {}^{3}F_{4}\rightarrow 3d^{8}4s4p {}^{3}G^{\rm o}_{3}$$ and $Mathematical equation: $3d^{9}4s {}^{3}D_{3}\rightarrow 3d^{8}4s4p {}^{3}G^{\rm o}_{3}$$ transitions of ⁶³Ni and ⁶¹Ni isotopes. Experimental spectra allowed us to derive hyperfine interaction constants and determine the magnetic dipole moment of the nuclear ground state of ⁶³Ni for the first time: $Mathematical equation: $\mu=+0.496(5)\mu_{\rm N}$$ . The value obtained agrees well with the prediction of the self-consistent theory of finite Fermi systems.
