- 次の各段階を備える,単波長X線を用いたX線構造解析における回折斑点の強度算出方法。
(a)2次元のX線記録領域上に単結晶試料の回折斑点を複数個記録する段階。
(b)前記X線記録領域において,前記回折斑点のそれぞれについて,その中心位置を通過する回折角一定の曲線を求める段階。
(c)前記回折斑点のそれぞれを取り囲む強度算出枠であって,前記曲線に垂直な方向における第1寸法と,この第1寸法よりも大きくて前記曲線に沿った方向における第2寸法とを備える前記強度算出枠を,前記X線記録領域上に設定する段階。
(d)前記強度算出枠の内側の領域で前記X線記録領域上の回折X線の積分強度を求めて,これを前記回折斑点の強度とする段階。 - 請求項1に記載の強度算出方法において,前記強度算出枠の形状は長方形であり,前記第1寸法は前記長方形の短辺の長さに等しく,前記第2寸法は前記長方形の長辺の長さに等しいことを特徴とする強度算出方法。
- 請求項1に記載の強度算出方法において,前記第2寸法と前記第1寸法の差は,回折斑点の回折角が大きくなるほど大きくなることを特徴とする強度算出方法。
- 請求項3に記載の強度算出方法において,前記第2寸法と前記第1寸法の差は,回折斑点図の中心点から各回折斑点の中心までの距離に比例することを特徴とする強度算出方法。
- 請求項4に記載の強度算出方法において,前記比例する場合の比例係数を変更可能であることを特徴とする強度算出方法。
