In contrast to this the quantum crystal "solid helium" (in the foIlowing we shall only consider 4He} seems to exhibit no remarkable diffcrenccs with respect to ordinary solids. For example, solid helium was found to have well-defined crystal structures, specific heat and sound velocity measurements remained without surprise, and neutron scattering experiments led to the usual dispersion spectrum for phonons. After initial difficulties due to the large zeropoint motion the theoretical treatment of these phonons has been quite successful. Using techniques like self-consistent field methods, the calculations for the phonon frequencies are in fair agreement with all these experiments.</dcterms:abstract> <dc:format>application/pdf</dc:format> <dcterms:rights rdf:resource=""/> <void:sparqlEndpoint rdf:resource="http://localhost/fuseki/dspace/sparql"/> <dcterms:available rdf:datatype="">2011-03-24T14:52:31Z</dcterms:available> <dc:creator>Leiderer, Paul</dc:creator> <dc:creator>Hunklinger, Siegfried</dc:creator> <dspace:hasBitstream rdf:resource=""/> <dc:creator>Berberich, Paul</dc:creator> <dc:contributor>Dransfeld, Klaus</dc:contributor> <dcterms:hasPart rdf:resource=""/> <dcterms:isPartOf rdf:resource=""/> <dc:contributor>Berberich, Paul</dc:contributor> <dcterms:title>Lifetimes of hypersonic phonons in solid 4He</dcterms:title> <dc:language>deu</dc:language> <dcterms:issued>1974</dcterms:issued> <dc:contributor>Hunklinger, Siegfried</dc:contributor> <dcterms:bibliographicCitation>First publ. as paper in: Proceedings of the International Conference on Low Temperature Physics [LT-13] , Univ. of Colorado, August 21-25, 1972 , pp. 53-61</dcterms:bibliographicCitation> <dc:date rdf:datatype="">2011-03-24T14:52:31Z</dc:date> <bibo:uri rdf:resource=""/> <dc:creator>Dransfeld, Klaus</dc:creator> <dc:rights>Attribution-NonCommercial-NoDerivs 2.0 Generic</dc:rights> <dspace:isPartOfCollection rdf:resource=""/> <foaf:homepage rdf:resource="http://localhost:8080/jspui"/> <dc:contributor>Leiderer, Paul</dc:contributor> </rdf:Description> </rdf:RDF>
