In recent years, the reaction of the laser field assisted (e,2e) by physicist attachesgreat attention.Part of this study is discussed in coplanar non-symmetric geometry, Another partof the discussion in a non-symmetric non-coplanar geometry.calculations haveadopted a similar approach in Born.First, discuss the influence of the laser field on the peak of the binary peak.Usingthe asymmetrical non-coplanar experimental geometry condition,fixed Ei,β,ω,1remain unchanged,calculation of laser field and no laser field TDCS. Then simulateTDCS corresponding images,which studies the effect of laser field for tripledifferential scattering cross section.Under the condition of the asymmetrical coplanargeometry,laser field of TDCS in the process of binary peak has a certainimprovement.Second,under the condition of ignoring stark effect and quantum interferenceeffects, discuss the influence of electronic collision ground state of hydrogen in laserfield for TDCS, and adopt the non-symmetric non-coplanar geometry,application thefirst Born approximation method.From the calculations and the graphics of electroncollisions ground state of the hydrogen atom,and observation differential scatteringcross section by presence or absence of the laser field.we can find out that the resultof the laser field has a certain influence on the scattering process.;Then discuss theinfluence factors of TDCS in the presence of the laser field, This process is analyzedin three aspects,Then with the way of control variables,the various factors discussedwhat impact the image of TDCS in the presence of a laser field.
