Professor Khakoo will measure absolute differential cross sections of electron impact excitation on Helium atoms. The excitation will populate excited levels of Helium which subsequently decay by radiation. Coincident measurement of the electron energy at fixed scattering angle together with the emitted photons will test fundamental assumptions of approximate theories of electron-atom scattering at intermediate energies.

卡库教授将测量氦原子上电子碰撞激发的绝对微分截面。激发将填充氦的激发能级，而氦随后会因辐射而衰变。在固定散射角下的电子能量与发射的光子的符合测量将检验中等能量下电子-原子散射近似理论的基本假设。
