| Abstract: | In this paper,by means of a full quantum theory,we have obtained the general fomula of steady photoelectron energy spectrum in a system of the Raman-type atom interacting with a twomode field,The influences of photon distributi0n of driven field on the steady photoelectron energy spectrum are investigated - The properties of atomic c0herent trapping related to the correlation characters of photons between the mode 1 and the mode 2 are analysed,And the condition appearing as the comb confluences of coherence is also verified． |
