_refln.sin_theta_over_lambda

Name:
_refln.sin_theta_over_lambda

Aliases:
_refln_sint/lambda
_refln_sin_theta_over_lambda
_refln.sint_over_lambda

Definition:

   
     The (sin theta)/lambda value for this reflection.

Type: Real

Units: reciprocal_angstroms

The permitted range is 0.0 → infinity

Evaluation method:

     With r  as  refln
                            h =  r.hkl
                            G =  _cell.reciprocal_metric_tensor
 
     r.sin_theta_over_lambda  =   Sqrt ( h * G * h ) / 2.
