We have studied mutual projectile and target ionization in 1-MeV/amu N(4+) and N(5+) + He collisions in kinematically complete experiments by measuring the momenta of the recoil ion and both ejected electrons in coincidence with the charge-changed projectiles. By means of four-particle Dalitz plots, in which multiple differential cross sections are presented as a function of the momenta of all four particles, experimental spectra are compared with theoretical results from various models. The experimental data are qualitatively reproduced by higher-order calculations, where good agreement is achieved for N(5+) + He collisions, while some discrepancies persist for N(4+) + He collisions.
