摘要：
The spectra of electrons emitted during the collision of slow He+ ions with metal surfaces are calculated. We consider the Auger neutralization process to be responsible for the electron emission. The main ingredients in our calculation of the Auger transition rate are the energy level variation of the ls state of He and the effective electron density n(z) which takes care of the electron tunneling through the metal-atom potential well. Our results are compared with available experiments for Cu.
