Claus Mueller Gatermann

Claus Mueller Gatermann is a researcher at Argonne National Laboratory within the Physical Sciences and Engineering division's Physics department, specializing in low-energy nuclear physics. He joined Argonne in 2020 after leading the FN tandem accelerator complex at the University of Cologne.

His educational background includes:

• Diploma in Physics, University of Cologne, Germany (2015)
• Doctorate (Dr. rer. nat.) in Experimental Physics, University of Cologne, Germany (2019)

Dr. Gatermann's research centers on nuclear structure physics, particularly the evolution of collectivity in nuclei far from beta stability. His expertise encompasses gamma-ray spectroscopy, Doppler-shift lifetime measurements, and innovative plunger device design (e.g., iCAPS). He actively fabricates specialized targets—including Actinide targets at the Center for Accelerator Target Science (CATS)—for experiments investigating shape coexistence and single-particle/collective excitation dynamics near Lead/Tin shell closures and the N=Z line.

He conducts experiments using integrated detector systems like Gammasphere/GRETINA coupled with Microball, Neutron Shell, and recoil separators (FMA/AGFA). His Lab Directed Research and Development (LDRD) project developed the compact iCAPS plunger setup for high-efficiency measurements. Affiliated with the Low Energy Physics group, he utilizes Argonne's Radioactive Material Handling Laboratory and Target Fabrication Facility while maintaining collaboration with the University of Cologne.
