We, the Research Group Sfienti of the Institute for Nuclear Physics at the Johannes Gutenberg-University Mainz, welcome you to our homepage. We hope you find all the information you need, and look forward to your visit.
News from our group
Fancy studying neutron stars without leaving Earth?
We are recruiting a PhD student in Nuclear Astrophysics. We use accelerator-based experiments to understand the properties of neutron stars and the nuclear reactions that power stars.
Join us in Mainz and work on the nuclear physics behind stars
Open call for applications: June 8 to July 8, 2026

To boldly measure where no one has measured before...
With our next transverse asymmetry beam time at A1, we go for the final frontier: taking data with a 208Pb target at 210 MeV!
The beam time will run from the 17th of November until the 2nd of December.
Felix Heim has successfully completed his bachelor thesis studying the feasibility of measuring the photodissociation of 6Li in electron scattering with the A1 spectrometer apparatus at MAMI and was awarded the degree of Bachelor of Science (B.Sc.).
In his thesis he estimated the expected event rate of the reaction 6Li(e, e' α)d using the MAGIX simulation framework and studied the properties of the inevitable background due to the target design using the FLUKA simulation software package.
Congratulations to Felix and all the best for his further studies!
