Absolute single electron loss in collisions of Ar+ with various atoms

Absolute differential and total cross sections for single electron loss were measured for Ar+ ions on various atoms in the energy range of 1.5 to 5.0 keV. The laboratory angular scan for the distributions ranged from -2.5 to 2.5 degrees. The measured differential cross sections have been integrated over the experimental angular range providing absolute total cross sections. The behavior of the total electron loss cross sections with the target atomic number, Z(t), shows different dependences as the collision energy increases. In all cases it displays a saturation as Zt increases
