| Abstract: | Within the framework of the first-order Born approximation,the triple differential cross sections(TDCSs) for simultaneous ionization and excitation of helium are calculated.The wave function of the ejected electron is chosen to be orthogonal or non-orthogonal to the wave function of the bound electron before ionization.It is found that the orthogonality has a strong effect on the TDCS,especially when plane waves and Coulomb waves are used to describe the projectile and the ejected electron. |
