  • BASELINE CORRECTION SYSTEM AND EVALUATION OF MAGNETIC FIELD STRENGTH FOR THE MEASUREMENT OF THE HYPERFINE STRUCTURE OF Rb ATOMS IN SUPERFLUID HELIUM

抄録

We have been developing a laser spectroscopic method for atoms injected into superfluid helium (He II). We aim to measure hyperfine structure splitting which is caused by interaction between nuclei and valence electrons under the circumstance of He II. However, it has been difficult to realize measurement with sufficiently high precision due to the fluctuation of the number of observed photons when we use two-step laser sputtering method to supply atoms into He II. To overcome this difficulty, a baseline correction system to cancel the fluctuation of the number of atoms was developed. In this study, we performed an RF double resonance experiment for Rb atoms injected into He II using the baseline correction system. And we evaluated the precision of the magnetic field strength applied to the atoms which will be utilized for the measurement of the hyperfine structure.
