_atom_site_aniso.U_22

Definition:

   
     These are the standard anisotropic atomic displacement
     components in angstroms squared which appear in the
     structure factor term:
     
    T = exp{-2pi^2^ sum~i~ [sum~j~ (U^ij^ h~i~ h~j~ a*~i~ a*~j~) ] }
    
     h = the Miller indices
     a* = the reciprocal-space cell lengths

     The unique elements of the real symmetric matrix are entered by row.

Type: Real

Units: angstrom_squared
