Abstract

The Au atomic Mα characteristic Xray spectrum has been measured for the slow highly charged ions Ar^q+ (q= 7—14) impacting on Au surface. The result shows that as long as the charge state of projectile is higher（q=11）， the characteristic Xrays of heavy atomic can be effectively excited even though the ionic beam is very weak(nA magnitude)， and the single ionic Xray yield is in the order of 10^-8 and increases with potential energies of projectiles.
