Homework Statement
Unit cell of a crystal lattice is a parallelepiped spanned by the vectors u, v, w vectors have lengths of 1, 2 resp3 (le). angles between the vectors is
[u, v] = pi / 4
[u, w] = pi / 3
[v, w] = pi / 6
Determine the volume of the unit cell.
Homework Equations
How do you solve this problem?
The Attempt at a Solution
volume = V (w, u, v) = w scalar with (u x v)
I can determine | uxv | = sqrt (2)
if I can find out the angle between
w and uxv then the problem is solved but it is not possible to get this angle.
