Hyperfine structure of electronic levels and the first measurement of the nuclear magnetic moment of 63Ni

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