Definition

quantity given by:

F (h, k, l) = \sum_{n = 1}^{N} f_{n} exp [2 π i (h x_{n} + k y_{n} + l z_{n})]

where $f_{n}$ is the atomic scattering factor (atomic scattering factor) for atom $n$ , $x_{n}$ , $y_{n}$ , $z_{n}$ are fractional coordinates of its position, $N$ is the total number of atoms in the unit cell and $h$ , $k$ , $l$ are the Miller indices

grandeur donnée par :

F (h, k, l) = \sum_{n = 1}^{N} f_{n} exp [2 π i (h x_{n} + k y_{n} + l z_{n})]

où $f_{n}$ est le facteur de diffusion atomique (atomic scattering factor) pour l'atome $n$ , $x_{n}$ , $y_{n}$ , $z_{n}$ sont les coordonnées fractionnaires de sa position, $N$ est le nombre total d'atomes dans la maille élémentaire et $h$ , $k$ , $l$ sont les indices de Miller
