within the framework of the Hessian Cluster Project ELEMENTS for a funding period of three years initially.


The Cluster Project ELEMENTS is a collaborative project of Goethe University Frankfurt, TU Darmstadt, JLU Gießen, and the GSI Helmholtz Center for Heavy-Ion Research. It addresses the physics of binary neutron-star mergers from gravitational waves to the equation of state (EOS) of neutron-rich nuclear matter.


The successful candidate will participate in studies of heavy and superheavy nuclei, for example through high-precision mass spectrometry with the SHIPTRAP setup at the GSI Helmholtzzentrum in Darmstadt.


Your tasks:


  • develop novel mass spectrometric methods for the study of exotic nuclides in the region of the heaviest elements
  • participate in experiments for the investigation of actinides and transactinides by Penning-trap mass spectrometry
  • set up, develop, and optimize customized data acquisition and data analysis systems


Your Qualification:


  • M.Sc. in physics with a focus on experimental work in atomic physics, nuclear physics, or nuclear chemistry
  • good communication skills in English (both verbal and written)
  • experience in mass spectroscopy and the operation of ion traps desirable
  • knowledge in software development for experiment control and data analysis desirable


We offer a fixed-term 3-year position with the salary and benefits based on the Collective Agreement for the German Public Service (TVöD-Bund) effective at GSI and can include a Ph.D. at Johannes Gutenberg University in Mainz.


Salary is equivalent to that for public employees as specified in the collective agreement for public employees (TVöD Bund).


GSI supports the vocational development of women. Therefore, women are especially encouraged to apply for the position.


Handicapped persons will be preferentially considered when equally qualified.
