Abstract
The hyperfine structure of the resonance lines of108mAg and110mAg has been investigated by means of optical interference spectroscopy. The metastable isotopes were produced by neutron irradiation in a reactor. From the measureda- andb-values we derive the value for the nuclear magnetic dipole moment of108mAgμ I (108m)=3.577 (20)μ n and the values for the electric quadrupole momentsQ I (108m)=1.52(8) bQ I (110m)=1.65(10) b (without Sternheimer correction). The measured isotope shifts allow the determination of the changes in the mean square charge radii of the nuclei involved:δ 〈r 2〉(108m-107)=0.022(3)fm2 δ 〈r 2〉(110m-109)=0.029(2)fm2.
The isotope positions show odd-even staggering comparable with those of neighbouring isotonic nuclides.
