In the method, He II is used as an efficient stopper for highly energetic ion beams and as an in-situ laser spectroscopic environment. Recently, we conducted an ion stopping experiment for the energy of approximately 350 AMeV 84Rb37+ at QST-HIMAC. Radioactive 84Rb ions were produced via projectile fragmentation reaction using accelerated 84Kr36+ and 12-mm thickness Be target. As the first step, we measured the stopping range of the injected ion beam using liquid N2 to estimate the stopping range in He II and the spot size of the injected ion beam using a plastic scintillator. Then, laser-induced fluorescence (LIF) detection experiment was performed using He II. We successfully observed the LIF from 84Rb atoms. We estimated stopping range of 84Rb ions in superfluid helium from the obtained results. The details of experiment at QST-HIMAC and results are given in this report. description_type: abstract lang: en - description: "We are developing a laser spectroscopic method for the study of nuclear structure\r\nof radioactive isotope utilizing superfluid helium (He II).
