Abstract: | The magnetic field effect of a8S7/2-z6P7/2 lines of 151Eu and 153Eu in magnetic fields up to 66.7 mT has been studied by using laser atomic beam spectroscopy. The Zeeman level structures of the europium a8S7/2 and z6P7/2 states in magnetic fields were discussed. The location and intensity of the measured Zeeman transition lines were found in good agreement with the theoretical results. |
