摘要：
Electron Raman scattering of a two-electron quantum dot is studied by means of the exact diagonalization and the second-perturbation approach methods. The differential cross section of Raman scattering is obtained. Effects of the external magnetic field and the confinement strength on the differential cross-section are investigated. The results show that the Raman scattering is an experiment that would allow us to probe the angular momentum transitions of the ground state as the magnetic field is varied. (C) 2013 Elsevier B.V.
