【 摘 要 】
Synopsis We present theoretical study of energetic electron-impact excitation of "six-level helium atom" embedded in a laser field. During the scattering process, the combined interactions lead to a change in the kinetic energy and the angular distribution of the scattered electron. The latter contains all information about the combined interactions. The analysis of the angular distribution reveals the emergence of a peak profile. This is will be discussed in terms of quantum-path interferences in boundbound electronic transitions. Furthermore, the sensitivity of the phenomenon to the collision dynamics will also be discussed.
