Implication

Experimental study reports absolute ionization cross sections for argon from threshold to 1000 eV, highlighting improved measurement accuracy with an uncertainty of ±3.5%.

Key Points

To measure absolute partial and total cross sections for electron-impact ionization of argon from threshold up to 1000 eV.
Employed a time-of-flight mass spectrometer integrated with position-sensitive detection of product ions across energies up to 1000 eV.
Incorporated refined pressure measurement and particle detection techniques to isolate Arⁿ⁺ (n=1–4) ions.
Determined total cross sections by taking an appropriately weighted sum of the measured partial cross sections.
Obtained absolute partial cross sections for the generation of Ar⁺, Ar²⁺, Ar³⁺, and Ar⁴⁺ along with total cross sections up to 1000 eV.
Demonstrated an overall absolute uncertainty of ±3.5% for singly charged argon ions (Ar⁺).
