Subject Area

Term
since 2016
Project identifier
Deutsche Forschungsgemeinschaft (DFG) - Project number 279384907
Project B02 provides experimental constraints for electroweak interactions in nuclei and nuclear-structure aspects relevant to nuclear astrophysics. We will focus on the isovector spin M1 strength, the electromagnetic analog of their Gamow-Teller strength, by a complete quantification of the M1 and E1 excitation strength distributions from measurements at the S-DALINAC in Darmstadt and at HIgS, USA. The combination of experiments using nuclear resonance fluorescence and electron-gamma coincidence spectroscopy will provide absolute M1 excitation strengths up to the particle threshold for N=50 nuclei. These data will be confronted with shell-model calculations and will benefit the modelling of core-collapse supernovae.
