Ion beam analysis (IBA) techniques are often used to study works of art,  because of their noninvasive and nondestructive character. These techniques exploit the products of interactions between beams of accelerated charged particles and the target in order to determine its elemental composition.</skos:scopeNote><skos:inScheme rdf:resource="http://AATesaurus.cultura.gencat.cat/aat/getty_en"/><skos:broader rdf:resource="http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31298665"/><skos:narrower rdf:resource="http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31317480"/><skos:narrower rdf:resource="http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31317483"/><skos:narrower rdf:resource="http://AATesaurus.cultura.gencat.cat/aat/getty_en?tema=31317486"/><skos:exactMatch> <skos:Concept rdf:about="http://AATesaurus.cultura.gencat.cat/aat/getty_es/index.php?tema=14053608"> <skos:prefLabel xml:lang="es">ion beam analysis (traducció pendent)</skos:prefLabel> </skos:Concept></skos:exactMatch><skos:exactMatch> <skos:Concept rdf:about="http://AATesaurus.cultura.gencat.cat/aat/getty_ca/index.php?tema=9823722"> <skos:prefLabel xml:lang="ca">ion beam analysis (traducció pendent)</skos:prefLabel> </skos:Concept></skos:exactMatch>  <dct:created>2026-03-30 20:21:54</dct:created>  </skos:Concept></rdf:RDF>
