Abstract The three-body distorted-wave Born approximation has been used to calculate the (e, 2e) triple differential cross sections (TDCSs) of Cu⁺ (3p) in different kinematical variables in coplanar asymmetric geometry. The angles 4o, 10o and 20o were selected as the scattering electron angles. Under high incident energy (≥ 500 eV) and high asymmetric detection energy, the binary peaks showed abnormal splits. Such abnormal splits have not been observed in atomic target and outer valence orbitals of ionic target, which indicates that an (e, 2e) process for inner valence orbitals of ionic target would be more complicated than outer valence orbitals. Furthermore, some pronounced peaks appeared at certain ejected angles. We considered that these pronounced peaks are probably related to one kind of double-binary collision.
