Nuclear physics experiments for the astrophysical process

We studied the two astrophysically interesting reactions 141 Pr ( α , n ) 144 Pm and 92 Mo ( p , γ ) 93 Tc with the activation method and with the in-beam method, respectively. The 141 Pr ( α , n ) 144 Pm experiment was performed at the cyclotron of the ‘Physikalisch Technische Bundesanstalt (PTB)’ in Braunschweig, Germany, and the reaction was studied within and just above the so-called Gamow window. In this proceedings, we present the experimental details of this measurement. The proton-capture reaction on the neutron-magic nucleus 92Mo was studied at energies relevant for the astrophysical p process. The reaction was investigated by the in-beam technique using the γ -ray detector array HORUS (High efficient Observatory for γ -Ray Unique Spectroscopy) at the TANDEM ion accelerator at the University of Cologne. The preliminary experimental results are compared to data stemming from other measurements.
