Analysis of Natural Diamonds by Rutherford Backscattering

The method of Rutherford backscattering (RBS) of 4 He ions is used to detect impurities in the surface region of natural diamond crystals. In order to decrease the influence of luminescence from the surface of diamond, the recording of scattered ions is performed by an annular detector, which decrea...

Description
Summary:The method of Rutherford backscattering (RBS) of 4 He ions is used to detect impurities in the surface region of natural diamond crystals. In order to decrease the influence of luminescence from the surface of diamond, the recording of scattered ions is performed by an annular detector, which decreases the statistical error and improves the measurement accuracy. The limit of impurity detection is 10 14 at/cm 2 for light impurities and 10 12 at/cm 2 for heavy impurities.
