In wikipedia http://en.wikipedia.org/wiki/Quadrupole
Is this [tex]\delta_{i,j}[/tex] Kronecker delta?
In my notebook I have relation:
[tex]Q_{i,j}=\frac{3}{2}eQ_0(x_ix_j-\frac{1}{3}\delta_{i,j})[/tex]
When direction of external field are the direction of symmetry axis [tex]Q=Q_0[/tex].
In which book I can find more about this?
