| Outline of Final Research Achievements |
The possibility of new physics search in the order of several microns was explored by measuring the length scale of the quantum bound state of ultracold neutrons in the gravitational field precisely and verifying the influence of known interactions. The probability distribution of ultracold neutrons shows a modulated distribution due to the quantum effect and we have investigated ways towards the improvement of modulation contrast within the period of this research.

| Academic Significance and Societal Importance of the Research Achievements |
質量などを結合荷とするような新物理探索を行う可能性を調べるのが、本研究の目的である。素粒子標準理論が確立しておりそれを越える新しい物理の手掛りが見付かっていない現状で、技術的に困難を共なっていたためにこれまであまり行われてこなかった研究対象へアプローチすることのできる可能性を秘めたもので、学術的・社会的意義は高い。
