Selectivity of X-Ray Detection by a Variable Geometry Proportional Counter


THERE are two reasons for the growing interest in the generation of characteristic X-rays by heavy particle bombardment1 as opposed to electron irradiation. The resultant X-rays are virtually free from white background radiation, so that even the lightest elements can be detected; and the technique can be allied to the phenomenon of channelling to yield a… (More)
