Web1 apr. 2024 · What I mean by 'contribution' is how much of the atom in that lattice point belongs to one unit cell. Eg:- in CCP packing the contribution of atoms at the corners is 1/8 th. I know that in a CCP unit cell the octahedral voids are there at the body center and the edge centers- so the contribution of an atom from both locations is different- 1 and 1/4 th. Web10 jul. 2024 · Thus, the octahedral interstitial site with $\frac{r}{R}$ ratio of $0.414$ in FCC is the larger one between two sites, while that in the BCC is the tetrahedral interstitial site with $\frac{r}{R}$ ratio of $0.291$. Note that the $\frac{r}{R}$ ratio of the tetrahedral interstitial site of FCC is the value of $0.225$.
