Charge radii studies through laser spectroscopy

Iimura, Hideki  

Because nuclear charge radii have recently been calculated by including the 3-body interaction, it is interested very much to confirm experimentally this theory. Up to now, high-resolution laser spectroscopy is the only way to measure the charge radii of unstable nuclides. In this seminar, methods of the laser spectroscopy for unstable nuclides is given together with the procedure to determine the change of charge radii from the isotope shifts. Also, progress of laser spectroscopy experiments in radioactive beam facilities in the world is reviewed. Finally, I will discuss a plan of laser spectroscopy experiment in RIBF to confirm the effect of 3-body interaction on nuclear charge radii.
