X-Ray Emission from Zr, Mo, In and Pb Targets Bombarded by Slow Highly Charged Ar^q+(q =13, 14, 15, 16) Ions

We study the L x-ray emission from Zr, Mo and In targets and M x-ray emission from Pb target under bombardment of low energy Ar^q+ (q=13,14,15,16) ions. The relative x-ray yields were measured in the projectile kinetic energy range 210--360keV. It is found that the relative x-ray yields from Zr, Mo and Pb targets increase with the increasing projectile kinetic energy for Ar¹⁴⁺ and Ar¹⁶ projectiles and depend on the potential energy of the projectile remarkably.
