Hi PF there is one thing that i cannot understand here.(adsbygoogle = window.adsbygoogle || []).push({});

Please look at eqn 1068

I try to compute the first term (without ##V^\dagger##)

I get someting like

##c_f (t) =-i/\hbar exp [i(\omega + \omega_{fi})t/2] \frac{sin(\omega + \omega_{fi})t/2}{(\omega + \omega_{fi})/2} \}##

Unlike eqn 1071 a "t" is lacking under the sine and i cannot write it as a sinc function.

Could you help me? I do not see my mistake.

(I can write my intermediate formulas)
