Paint layer studies using PIXE and RBS on air


Paint layer studies using PIXE and RBS on air

Wagner, W.; Neelmeijer, C.; Schramm, H.-P.

To identify layer structures of oil paintings and to determine their elemental composition, external beam PIXE and in addition external beam RBS have been applied simultaneously. The beam energy is varied to obtain depth information by means of PIXE. To check the evidence of the idea a set of test paint layers is prepared. It is found that a combination of the two ion-beam analysis techniques delivers the information needed. The pigment components of the test layers are detected and attached to the layers and additionally the layer thickness is determinable. As an example measurements on the historical painting "14 Nothelfer" (L. Cranach the elder) are presented which are gained by means of external PIXE at various proton energies coupled with external beam RBS.
