Implications of heavy-ion-induced satellite X-ray emission V Fine structure of the sulfur K X-ray satellite peaks

We have studied K _α X-ray emission induced by 34 MeV ³⁵Cl ions from several compounds at the ORNL EN Tandem Van de Graaff with a high-throughput, high-resolution Bragg crystal spectrometer in the Van Hamos geometry. The X-rays are diffracted off a cylindrically curved, highly reflective quartz crystal and detected with a position-sensitive proportional counter. The resolution of the spectrometer was better than one part in 2000. The data show remarkable and distinct fine structure in the individual KL ⁿ satellite peaks. Such data should aid in eventual comparisons with structures predicted by theoretical transition energy and intensity calculations.
