Collinear laser spectroscopy of high-energy Li-like11B beam

1997

As part of the RIKEN RIBF (RI beam factory) program, high-resolution x-ray spectroscopy for highly-charged radioactive isotope beams, is proposed in order to make a systematic study of the mean-square nuclear charge radii and moments of short lived radioactive isotopes far from the line of stability. To examine the feasibility of the experiment, we are now performing a test experiment using a laser beam and Li-like ion beams from RIKEN ring cyclotron. The D1 resonance line of a 11B2+ beam was clearly observed for the first time.
