Dear all Please be informed about the following QSIT Seminar. With best regards, Ilona Blatter ---------------------------------------------------------- Date: Friday December 17, 2010 Place: HPF G 6 Time: 11:00 Host: Jonathan Home g-factor measurements on hydrogen-like ions as a test of bound-state QED Joseba Alonso Johannes Gutenberg Universität, Mainz, Germany The precise determination of the anomalous magnetic moment of the electron bound in hydrogen-like ions allows for a stringent test of quantum electrodynamics (QED) in the presence of strong electric fields. g-factor measurements on the electron bound in hydrogen-like ions C5+ and O7+, using single ions confined in a Penning trap, have yielded values in agreement with theory on the ppb level. If the QED calculations are considered correct, the results can in turn be used for a determination of fundamental constants like the electron mass me, the fine structure constant α or nuclear parameters. We report about present developments towards g-factor measurements also in medium-heavy and heavy highly-charged ions. --------------------------------------------------- ETH Zurich Dr. Ilona Blatter QSIT Coordinator Laboratory for Solid State Physics HPF E 13 Schafmattstrasse 16 8093 Zurich ilona.blatter@phys.ethz.ch www.qsit.ethz.ch Phone: +41 44 633 36 06 Home: +41 44 844 42 50
