In the present work, the elastic scattering of an electron from the target by absorbing a photon from the laser field has been studied. Since the solution of the Schrödinger equation of whole three-body system has not been found, we consider such intensities of electromagnetic field (Laser field) that the electron field coupling is the dominant process and the target is transparent to the field such that photon- target coupling can be ignored. Internal structure of target can be ignored and represented just as a scattering potential. For number of photon, l = -1, i.e, absorption of a photon (inverse Bremsstrahlung), The differential scattering cross section of an electron depends upon the fourth power of the wavelength (λ4) and the intensity of the Laser field The certain values of laser parameters the differential scattering cross section of scattered electron decreases with increase in scattering angle and attains a minimum value of 0.1 barn and further increase in scattering angle also increases in differential scattering cross section and attains a maximum value of 0.3 barn.
