Absolute values for the total, one-, two-, and three-electron-transfer cross sections for Ar[sup [ital q]+] ions (8[le][ital q][le]16) colliding with argon at 2.3[ital q] keV laboratory energy were measured by the growth-rate method. The Ar[sup [ital q]+] ions were produced by the Cornell superconducting solenoid, cryogenic electron-beam ion source (CEBIS) and extracted at 2.3 kV. Selected charge states traversed a gas cell, after which they were detected and charge-state analyzed by the energy-retardation method and by a [pi]/ [radical]2 cylindrical electrostatic analyzer. The target gas pressure in the cell was measured directly by the orifice flow method used for absolute pressure-gauge calibration. The overall error in the Ar[sup [ital q]+] on Ar cross-section measurements is [plus minus]10%.
