| Research Abstract |
Rydberg atoms well known in atomic physics were employed in surface physics analysis. Especially, in order to measure a weak static electric field where measurement is difficult, an analysis system using Rydberg atom was designed and constructed. Although a static electric field is basic physics property, the measurement is very difficult since a probe itself disturbs the electric field as long as the probe is made of metal. In our system the probe doesn't disturb the electric field since the Rydberg atom as the probe is a neutral atom. Although the background electric field of 20mV/cm can be observed in current status, the further improvement of stabilization of laser, etc. remained as a next subject.
