Abstract
Cusp-electron production has been investigated in 0.5-1.5 MeV/u O7+ AT collisions. For this system, cusp electrons can result from electro n capture or loss to the continuum (ECC or ELC), transfer ionization ( TI), or double transfer ionization (2TI). Of particular interest are t he two- and three-electron processes TI and 2TI. The ratios TI/ECC and 2TI/ECC each exhibit a maximum near 0.75 MeV/u, while the ELC/ECC rat io increases monotonically with beam energy. The reasons for these beh aviors, including electron correlation effects, are considered.
