Description
The hyperfine structure of the D2 optical line in 22Na and 23Na has been investigated using high resolution laser spectroscopy of a well-collimated atomic beam. The hyperfine splitting constants A and B for the excited 3p2P3/2 level for both investigated sodium isotopes have been obtained. They are as follows: A(22)=7.31(4) MHz, B(22)=4.71(28) MHz, A(23)=8.572(24) MHz, B(23)=2.723(55) MHz. With this data, using the high precision MCHF calculations for the electric field gradient at the nucleus, the electric quadrupole moment of 22Na has been deduced: Qs(22)=+0.185(11) b. The sign of Qs(22), determined for the first time, indicates a prolate nuclear deformation. A precise value of the isotope shift 22,23Na in the D2 line has also been obtained. (orig.)
