T w o - P hoton Li thium S pectroscopy for the Charge Radius Determination of the Halo Nucleus Li-11 Principle of Charge Radius Determination Charge radii cannot be obtained in a model-independent way [...] either the 2 S -3 S or a 2 S -2 P transition is measured. The accuracy of the mass shift calculation for 11 Li is better than 200 kHz). Such a resolution can only be obtained by cw laser spectroscopy on a thermal

Nucleus Li-11 Results on 8,9Li The isotopes 8 Li and 9 Li have lifetimes of 840 ms and 178 ms respectively. They were produced at the GSI on-line mass separator by impinging 12 C ions at 11.4 MeV/u onto

Nucleus Li-11 The Charge Radius of 11Li In 2004, the experimental setup, developed and tested at GSI, was moved to the ISAC mass separator at TRIUMF . This facility offered us more than 30,000 11 Li ions/s [...] with 40 μA beam current. During two weeks of beamtime in October 2004 we obtained about 100 spectra of 11 Li like that shown in Fig.1. These scans were later combined to form single resonances like that one [...] the nuclear charge radius continuously decreases from 6 Li to 9 Li and significantly increases for 11 Li. In Fig.3 also recent nuclear theoretical predictions are shown. The best agreement for the nuclear
