Conditions de réflexion sériales (Fr).
The serial reflection conditions are the general reflection conditions due to the presence of screw axes. The resulting conditions apply only to onedimensional sets of reflections, i.e. reciprocal-lattice rows containing the origin (such as h00, 0k0, 00l). For instance, for a screw axis parallel to , the reflection conditions are:
|type of reflection||reflection condition||screw vector||screw axis|
|00l||l = 2 n||c/2||21; 42|
|l = 4 n||c/4||41; 43|
|000l||l = 2 n||c/2||63|
|l = 3 n||c/3||41; 31; 32; 62; 64|
|l = 6 n||c/6||61;65|
The serial reflection conditions are listed in Table 18.104.22.168 of International Tables of Crystallography, Volume A.
