Study Of The Interference-effect For Quantum-Scattering Assisted Of Laser Fields

Quantum scattering experiment in recent years,more and more get the attention of people,plays an important role in people's life,become an indispensable branch of modern physics.In laser assisted reaction,the very widespread attention,the so-called laser aided by ionization effect is to join after laser field.We use the method of control variables,the image of the simulation results of the study of the influence of some physical quantities,each physical simulation results is different.In this article,electronic impact of hydrogen was conducted on the basis of the reaction.Under the condition of coplanar geometry study the influence of a strong laser on the electronic impact of hydrongen,we selected of the final state wave function in the early is in the case of considering the stark effect.The wave functions of the incident and scattered electrons is treated as Volkov waves.When the wave functions changed due to some factors,then at the same time the image will be as the initial state of the wave function synthesis after changing.In the actual operation,we use a series of mathematical functions,such as Bessel function excited state of the concrete expression of the triple differential scattering cross section,We control the every physical quantity,further study on the different ejected electron energy and scattering Angle for hydrogen atoms from the triple differential scattering cross section in the process of impact.Through calculation we found that the strong laser field influence the electronicon spatial distribution,and peak value is higher than does not exist the laser field.The recoil peaks is relatively little difference,and binary has certain upward trend,With the increase of ejected electron energy and scattered angel,binary peak decline.And under the excited state,the binary peak divided.Binary peak divided weaken,correction of the peak state is far greater than without considering correction peak state.Fixed mode in the mixed state of peak decrease amplitude ratio did not consider fixed condition of the waves decrease.
