Electron impact excitation of hydrogen atom with anomalous magnetic moment effects

In framework of first Born approximation, Salamin wave states have been used to calculate the differential cross section for laser assisted semirelativistic 1s-2s excitation of hydrogen atom by electron impact with anomalous magnetic moment effects fully included. The obtained results have been compared with laser assisted relativistic differential cross section without such effects. It is found that the electron's anomalous magnetic moment effects in laser assisted 1s-2s excitation is very important particularly with increase of intensity. Good agreement with laser assisted differential cross section without anomalous magnetic moment effects is obtained when electron's anomaly 𝜅=4𝑎𝑒−=2(𝑔−2) is taken to be zero. (author)
