DESCRIPTION:Speaker: Thorsten Schumm\nhosted by Onur Hosten\nAbstract: Amon
 g all known isotopes\, Thorium-229 has the lowest nuclear excited state\, 
 only 8.4 eV above the ground state. This so-called “isomer” is accessi
 ble to VUV laser excitation and a plethora of applications at the interfac
 e of atomic and nuclear physics have been proposed\, including a nuclear c
 lock\, a gamma laser and a sensitive detector for variations of fundamenta
 l constants.After decades of attempts to determine the exact isomer energy
  and other nuclear properties\, we report on two experiments which resonan
 tly excite the isomer\, through X-ray pumping via the 2nd nuclear state a
 t 29 keV and direct excitation using a VUV laser.This marks the transfer o
 f precision laser spectroscopy into the field of nuclear physics.
