Lithium adopts a BCC structure at room temperature with a
lattice parameter equal to 3.51 Å.
a).Find the Li-Li pairs corresponds to the 3 shortest distances.
Assume the correlation is between a Li at (x,y,z) and the Li at the
origin, i.e. (0, 0, 0). For example, the shortest Li-Li pair (also
known as Li-Li correlation) is given by the Li at (0,0,0) and the
Li at (0.5, 0.5, 0.5). Your answer should only show the
cooridinates of the Li...
