Optical isotope shifts and changes in nuclear charge radii of stable Ti isotopes

Abstract

Isotope shifts and hyperfine structures in three optical transitions of TiI have been investigated by using laser induced resonance fluorescence in a collimated atomic beam. From the isotope shifts data, changes of the mean square charge radii of the stable titanium isotopes have been determined for the first time. Using a combined analysis with muonic atom data on root mean square nuclear charge radii, improved model independent 〈r2〉1/2 values for the odd-even Ti isotopes have been obtained.
