Cusp-electron production has been investigated in 0.5-1.5 MeV/u O7+ + Ar collisions. For this system, cusp electrons can result from electron capture or loss to the continuum (ECC or ELC), transfer ionization (TI), or double transfer ionization (2TI). Of particular interest are the 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 ratio increases monotonically with beam energy. The reasons for these behaviors, including electron correlation effects, are considered.
