Measurements of Charge Radii and Electromagnetic Moments of Nuclei Far From Stability by Photoionization Spectroscopy in a Laser Ion Source

摘要

The method of Resonance Ionization Spectroscopy in a Laser Ion Source (RIS/LIS) has been described. It enables one to carry out measurements of isotope shifts and hyperfine splittings for isotopes at the production rate about 10~2 atoms per second. The isotope shifts and hyperfine structures of ~(153,155)Yb, ~(154)Tm (I=9 and I=2) and ~(153)Tm (I=11/2) have been measured and isotopic changes of mean square charge radii and nuclear electromagnetic moments for these isotopes have been determined.
