Solid Interactions Elemental Targets

The experiments aiming at the determination of the charged pion mass use X-ray transitions from the intermediate part of the atomic cascade, where the influence of the hadronic interaction can be neglected. The two most recent experiments both measured the (5from different elements. In one case, a solid state Mg target was taken [15,16], whereas the most recent experiment used an N2 gas target [12,17]. 

Several motivations exist for studying ion/solid interactions in multielement targets such as compounds and alloys. Even for elemental targets, sputtering at high ion...
