_cell.volume

Name:
'_cell.volume'

Definition:

   Cell volume V in angstroms cubed.

   V = a b c (1 - cos^2^~alpha~ - cos^2^~beta~ - cos^2^~gamma~
              + 2 cos~alpha~ cos~beta~ cos~gamma~)^1/2^

   a     = _cell.length_a
   b     = _cell.length_b
   c     = _cell.length_c
   alpha = _cell.angle_alpha
   beta  = _cell.angle_beta
   gamma = _cell.angle_gamma
