Precision measurement of the muonic 5-4 transitions in Pb and 4-3 transitions in Ba as a test for the validity of QED

The 5 to 4 and 4 to 3 transitions in muonic Pb and Ba, respectively, were measured with an accuracy of approximately 10 eV. Agreement with theoretical calculations is established. The vacuum polarization is tested to 3*10/sup -3/, and vacuum polarization corrections of higher order in ( alpha Z) to...

Sumario:The 5 to 4 and 4 to 3 transitions in muonic Pb and Ba, respectively, were measured with an accuracy of approximately 10 eV. Agreement with theoretical calculations is established. The vacuum polarization is tested to 3*10/sup -3/, and vacuum polarization corrections of higher order in ( alpha Z) to 20-30%. (76 refs).
