Abstract:The double electron loss (DEL) from He − has been investigated in collisions with He atoms at 300-keV impact energy and at electron energies that satisfy the cusp condition; i.e., the corresponding electron velocities match the projectile's velocity. In a time-of-flight experiment the energies of both electrons have been determined by detecting triple coincidences between the two electrons and the outgoing He + ion. The coincidence yield shows a peak as a function of the electron energies at the expected cusp … Show more
