Abstract

Laser resonant photoionization spectroscopy was used to study the hyperfine structure of the optical

and

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:

. The value obtained agrees well with the prediction of the self-consistent theory of finite Fermi systems.
