          The Helmholtz Institute Mainz (HIM) is an institutional cooperation of the Johannes Gutenberg-
          Universität Mainz and the GSI Helmholtz Centre for Heavy Ion Research GmbH in Darmstadt. It
          links the academic world of a university with the scientific possibilities of an internationally renowned
          unique large-scale accelerator center for ions. In the coming years the new international
          accelerator facility FAIR (Facility for Antiproton and Ion Research), one of the largest research
          projects worldwide, will be built at Darmstadt.

          The HIM research section Superheavy Element Physics invites outstanding candidates to apply
          for a

Postdoctoral Researcher Position in Laser Spectroscopy
Reference number: 21.02-4314

          for a two-year contract starting at the earliest possible date. The position will be located in

          The position is embedded in the project on laser spectroscopy of heavy and superheavy elements
          at the velocity filter SHIP at the GSI Helmholtzzentrum in Darmstadt. The project aims at the
          development and implementation of novel approaches in laser spectroscopy in combination with
          gas-stopping techniques and includes experiments with heavy actinides.

          The successful candidate is expected to
          • develop laser spectroscopic methods for the study of exotic nuclides in the region of the heaviest
          • participate in experiments for the investigation of actinides and transactinide by resonanceionization
          laser spectroscopy
          • set up, develop and optimize customized laser systems (dye- und solid state, pulsed and cw)
          • develop software for experiment control, data acquisition and data analysis
          • contribute to the supervision of Bachelor-, Master- und Doctoral students

          We expect
          • a PhD or equivalent degree in experimental atomic physics, nuclear physics, or nuclear chemistry,
          • sound experience in the field of laser spectroscopy, ideally with radionuclides,
          • experience in the operation of laser systems (dye- und solid state, pulsed and cw),
          • good communication skills in English (both verbal and written).
          Knowledge in software development for experiment control, data acquisition and data analysis is
