摘要：

We present experimental results for doubly differential electron emission in transfer ionization produced by H+ projectiles on a He target at 70 keV impact energy. Energy spectra were obtained at emission angles of theta = 0 degrees, 20 degrees and 50 degrees, and compared with spectra of total electron emission, these being dominated by single ionization. A cusp-shaped emission of electrons at the velocity of the emerging H-0 projectiles, and an enhanced electron emission from binary-encounter collisions are observed in the transfer ionization spectra.
