| Abstract: | The following three issues are described.At first, the essence of the Colson theory for the spontaneous emission in FEL is analysed. Then, using Gell-mann and Goldberger two-potential scattering formula, a new expression of the transition matrix element for the spontancous emission in FEL is derived. At last, the differences and relations between the new expression and the Colson's one are analytically discussed and a possilbe application of the new formula is predicted. |
