20201201 SWEDEN TETRAHEDRAL OCTAHEDRAL INTERSTITIAL SITES BCC

A standard crystallography diagram showing the tetrahedral and octahedral interstitial sites within a body-centred-cubic (BCC) metal lattice, the small gaps between packed atoms where smaller interstitial atoms such as carbon or hydrogen can sit, each site labeled with its geometric bond lengths in terms of the lattice constant a. This is textbook materials-science content; the archive filename's Sweden tag could not be matched to a specific institution or paper.
