摘要:We studied the proton-capture reaction on the neutron-magic nucleus 92Mo at energies relevant for the astrophysical p process. The reaction was investigated by the in-beam technique using the g-ray detector array HORUS (High efficient Observatory for g-Ray Unique Spectroscopy) at the TANDEM ion accelerator of the University of Cologne. The preliminary experimental results are compared to data stemming from two different activation measurements. Furthermore, the experimental data sets are compared to statistical model predictions. Additionally, we present our new 6 MV Tandetron for Accelerator Mass Spectrometry (AMS), which is currently installed at the University of Cologne. It can be used to detect very small concentrations of long-lived radionuclides which have e.g. been produced by cosmic events or in the laboratory. The combination of experimental approaches available at the University of Cologne gives access to a large number of astrophysically relevant reactions and allows detailed investigations of some key reactions within the p process network.
