N2 - Heavy ions passing through a magnetic field region filled with gas experience atomic charge-changing collisions and follow trajectories approximately determined by the mean charge state in the gas. The properties of a gas-filled Enge magnetic spectrograph are studied in detail by measuring focal-plane position spectra of fast heavy ions and their evolution as a function of gas pressure. The method allows physical separation of pairs of isobaric ions in the focal plane. Applications in accelerator mass spectrometry 0experiments are described. At intermediate low pressures, single atomic charge-changing processes can be identified. A Monte Carlo simulation program of the ion transport through the gas-filled magnet is developed and reproduces closely the experimental behavior.
