_cell.reciprocal_length_b

Name:
'_cell.reciprocal_length_b'

Definition:

   The reciprocal cell length (recip-b) in inverse Angstroms.
              (recip-a), (recip-b) and (recip-c) are related to the real cell
              by the following equation:

   recip-a = b*c*sin(alpha)/V

   recip-b = c*a*sin(beta)/V

   recip-c = a*b*sin(gamma)/V

   where V is the cell volume.
