Outline of Final Research Achievements

For realization of the interaction-free measurement in X-ray region, a pilot study was performed using X-ray Mach-Zehnder interferometer. Obtained experimental result in X-ray region using X-ray interferometer was equal to that in visible-light region. At the same time, we found out that stability of X-ray interferometer has a fatal influence.
At the present time, we judged that any more study continuation was impossible except performing an extra-large-scale stabilization measure of interferometer.
