The nuclear spectroscopy of 229Thorium is a highly interesting research field of nuclear and nuclear physics, which deals with the properties of an exceptionally low excited state in the atomic nucleus of 229Thorium. This state has an estimated excitation energy of only about 8 eV. Recently, it has been possible for the first time to stimulate this state directly with an optical laser. As part of the HiTHOR project, located at the Helmholtz-Institut Jena and funded by the European Research Council ERC, this nuclear transition will now be investigated in detail, which promises unique new insights into the quantum physics of nuclear nuclei and new approaches to the construction of a high-precision “core watch”. Within this project, the further development of a frequency comb laser in the vacuum ultraviolet (VUV) spectral range is of central importance and represents the central theme of a planned doctoral thesis. In close cooperation with experts at DESY in Hamburg as well as other collaborative partners, a new approach to the realization of a powerful VUV comb is to be followed, thus enabling direct laser nuclear spectroscopy at 229 thorium.

a completed Master's or Diploma in Physics, interest (and possibly experience) in the field of laser physics / nonlinear optics, Interest in cooperation with experts in an interinstitutional collaboration project very good English knowledge in word and writing (German knowledge is desirable) and strong team skills.

A varied activity in an internationally renowned research institution, embedded in the largest German organization for the promotion and financing of science. The body is limited to three years. The salary is based on the TVöD collective agreement (Bund). The Helmholtz Centre DESY is located in Hamburg.

GSI promotes the professional development of women and welcomes women to feel particularly addressed by the call for proposals. Highly disabled persons receive the benefit of the same qualification. .
