& \bar{E}(\bar{r},t)=\int_{0}^{\infty }{d\omega }{{{\bar{E}}}_{0}}(\omega )\sin \left( \bar{k}\bar{r}-\omega t \right) \\
& \Rightarrow {{W}_{nn0}}=\frac{\pi }{2{{\hbar }^{2}}}\int_{0}^{\infty }{d\left( \hbar \omega \right)}{{\left( {{{\bar{E}}}_{0}}\left( \omega \right)\cdot {{{\bar{d}}}_{nn0}} \right)}^{2}}\left\{ \delta ({{E}_{n}}-{{E}_{n0}}-\hbar \omega )+\delta ({{E}_{n}}-{{E}_{n0}}+\hbar \omega ) \right\} \\
