| Research Abstract |
The target of this research is to measure and prolong a spin coherence time of atom with spin degrees of freedom. As the first achievement, I designed and constructed the simple cooled ion trap chamber toward the realization of long time coherence of an atomic ion. As the second achievement, I succeeded in observing the spin precession of spin-2 atomic gaseous Bose-Einstein condensate and improving the spin coherence time by using the spin echo technique.
