演題：Towards a measurement of the 229Th isomer transition
講師：Dr. Simon Philipp Stellmer
（Institute of Atomic and Subatomic Physics,Vienna University of Technology）
Excitation of the isomeric state through an optical transition requires us to tightly confine the nuclei in a well-controlled electronic state. Among other options, such as ion traps, VUV-transparent crystals appear to be suitable platforms. The research activities of the Thorium group in Vienna are centered about 229Th:CaF2 crystals. A number of studies have been performed to characterize the relevant properties of our home-grown CaF2 crystals, and I will report on the latest measurements.
