As a strange property not explained by existing theories, it has been known from experiment that X-ray moiré and Pendellösung interference fringes show a small spatial oscillation in the beam path in free space that the diffraction image carrying those fringes is propagated after emerging from the crystal. In connection with the investigation into this(More)
As a complement to a previous paper reporting the anomalous fringe oscillation in X-ray Pendellösung interference fringes [Yoshimura (2000), J. Synchrotron Rad. 7, 374-381], this paper presents an amplitude map of the Pendellösung fringe oscillation in order to show that the amplitude distribution has a specific meaningful pattern within the topographic(More)
A detailed and comprehensive theoretical description of X-ray diffraction moiré fringes for a bicrystal specimen is given on the basis of a calculation by plane-wave dynamical diffraction theory. Firstly, prior to discussing the main subject of the paper, a previous article [Yoshimura (1997). Acta Cryst. A53, 810-812] on the two-dimensionality of(More)
The bond strength between composites and various particle sizes of glass-ionomer cements was investigated. The best bond strength was obtained after use of a small-particle cement and with the highest powder-to-liquid ratio employed for mixing the cement. In addition, use of a small-particle cement and the highest powder:liquid ratio produced cements with(More)
It has been experimentally found that X-ray moiré fringes are not exactly given as a projected figure from the specimen crystal as predicted by the standard theory of X-ray dynamical diffraction, but show a kind of spatial oscillation along the beam path out of the crystal. This paper reports that a similar spatial oscillation has been found for(More)
