Nettet16. jun. 2016 · So, we'll begin first then by looking at what we mean by the idea of a linear density. And this is describing for us the directions in which we have the most number of spheres that are along a line. So for example, if we look at our two structures, the BCC and the FCC, again on the left for the FCC structure.
