Here we demonstrate the compression of single-electron pulses with a de Broglie wavelength of 0.08 ångström to a full-width at half-maximum duration of 28 fs or equivalently 12-fs root-mean square, substantially shorter than most phonon periods and molecular normal modes. Atomic resolution diffraction from a complex organic molecule is obtained with good signal-to-noise ratio within a data acquisition period of minutes. The electron-laser timing is found to be stable within 5 fs (s.d.) over several hours, allowing pump-probe diffraction at repetitive excitation. These measurements show the feasibility of laser-pump/electron-probe scans that can resolve the fastest atomic motions relevant in reversible condensed-matter transformations and organic chemistry.</dcterms:abstract> <void:sparqlEndpoint rdf:resource="http://localhost/fuseki/dspace/sparql"/> <dc:rights>terms-of-use</dc:rights> <dc:contributor>Baum, Peter</dc:contributor> <dc:date rdf:datatype="">2018-09-14T11:54:16Z</dc:date> <dc:contributor>Krausz, Ferenc</dc:contributor> <dc:creator>Baum, Peter</dc:creator> <dspace:hasBitstream rdf:resource=""/> <dcterms:rights rdf:resource=""/> <dc:creator>Walbran, Matthew</dc:creator> <dcterms:available rdf:datatype="">2018-09-14T11:54:16Z</dcterms:available> <dcterms:title>Sub-phonon-period compression of electron pulses for atomic diffraction</dcterms:title> <dc:contributor>Gliserin, Alexander</dc:contributor> <foaf:homepage rdf:resource="http://localhost:8080/jspui"/> <dcterms:issued>2015-10-27</dcterms:issued> <dc:creator>Krausz, Ferenc</dc:creator> <dc:creator>Gliserin, Alexander</dc:creator> <dspace:isPartOfCollection rdf:resource=""/> </rdf:Description> </rdf:RDF>
