The isotope shifts of gadolinium isotopes with A = 146-160 have been determined by the method of resonance photoionization of atoms. The isotope change of the charge radii was calculated from the measured isotope shifts. These calculations, along with the known charge radii of stable Gd nuclei, were used to determine for the first time the mean-square charge radius of the ,46Gd magic nucleus: (r*)i/2C46Gd) =4.984 fm.
