【 摘 要 】

We present a newly built reaction microscope for electron induced ionization-excitation of helium. Kinematically complete measurement with 2p state excitation is achieved by detecting the radiated photon, one electron and the He+ion in the final state in triple coincidence. Near threshold behavior of the ionization- excitation to 2p state is investigated.
