_cell.reciprocal_angle_alpha

Name:
_cell.reciprocal_angle_alpha

Alias:
_cell_reciprocal_angle_alpha

Definition:

   
     Reciprocal of the angle between _cell.length_b and _cell.length_c.
     Ref: Buerger, M. J. (1942). X-ray Crystallography, p. 360.

Type: Real

Units: degrees


The permitted range is 0. → 180.

Evaluation method:

     With c as cell
 
    _cell.reciprocal_angle_alpha = Acosd(
    (Cosd(c.angle_beta)*Cosd(c.angle_gamma)-Cosd(c.angle_alpha))/(Sind(c.angle_beta)*Sind(c.angle_gamma)))
