Notre Dame Physicists Use Ion Beams to Detect Art Forgery

Published: January 20, 2012.
By University of Notre Dame

University of Notre Dame nuclear physicists Philippe Collon and Michael Wiescher are using accelerated ion beams to pinpoint the age and origin of material used in pottery, painting, metalwork and other art.

"A host of approaches with origins in biology, chemistry and physics have allowed scientists and art historians not only to look below a painting's or artifact's surface, but also to analyze in detail the pigments used, investigate painting techniques and modifications done by the artist or art restorers, find trace materials that reveal ages and provenances, and more," Wiescher and Collon continue.
