Abstract

Mass-separated samples of the unstable nuclides

{}^{128}{Ba}

(

T_{\frac{1}{2}} = 2.4

d) and

{}^{131}{Ba}

(

T_{\frac{1}{2}} = 11.5

d) have been investigated by means of Doppler-free laser spectroscopy, using cw dye lasers and a well-collimated atomic beam. From isotope shifts and hyperfine structure of the

{}^{1}S_{0} - {}^{1}P_{1}

transition (

λ = 553.6

nm) we obtained the differences of mean-square charge radii

δ 〈 r^{2} 〉 ({}^{131}{Ba} - {}^{130}{Ba}) = - 0.006 (3)

{fm}^{2}

and

δ 〈 r^{2} 〉 ({}^{130}{Ba} - {}^{128}{Ba}) = - 0.022 (3)

{fm}^{2}

and the magnetic moment of

{}^{131}{Ba}

μ = - 0.714 (6) μ_{N}
