Charge radii of thallium isotopes near the N = 126 shell closure

The changes in the mean-squared charge radius of Tl-209(g )(N=128) and Tl-207(m) (N=126) relative to Tl-205 have been measured for the first time using the in-source laser resonance-ionization spectroscopy technique with the Laser Ion Source and Trap (LIST) at ISOLDE (CERN). The application of the L...
