This is for body-centered cubic crystal structure.
Prove a = 4R/sqrt(3). R is the radius of sphere and a is the edge of the cell (cubic).
The image attached will be cut into cube so that 4 outter spheres' centers will be the edges of the cube, a.
n/a
Well, the disagnal from the farthest two points are 4R.
I tried to use one face to calculate the diagnal edge of the face and form a triangle with 4R and sqrt(2) but it won't work.
Something is wrong...please help!
