We have studied mutual projectile and target ionization in 1-MeV/amu N{sup 4+} and N{sup 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{sup 5+}+He collisions, while some discrepancies persist for N{sup 4+}+He collisions.
