SummaryThe radionuclide Tc-94m with its positron branching ratio of 72, positron end-point energy of 2.47MeV, and relatively short half-life of 52 minutes is suitable for quantitative measurements using PET. Tc-94m can be produced by proton bombardment of isotopically enriched [Mo-94]MoO

The neutron-deficient isotope Pr137 has been discovered by proton bombardment of natural cerium, chemical separation, and mass determination. Its half-life is 1.5 ± 0.1 hours and the end point of its positron spectrum is 1.7 ± 0.1 Mev. No gamma rays were observed.

With the new stage of the MAMI accelerator, the physics program on hadron physics at MAMI will be extended up to an end point energy of 1.5 GeV. A few selected experiments on electro production are presented to show examples on nucleon structure and baryon resonance structure studies. The photo production program at MAMI was described in a separate talk in this conference.

Abstract. Seven photo-neutron reactions 197Au(γ,xn)197-xAu (with x=1-7) produced by the bremsstrahlung end-point energy of 60 MeV were identified. In this work, we focus on the measurement of integrated sections. Experiments were carried out based on the activation method in combination with off-line gamma-ray spectrometric technique. The integrated cross sections of the investigated reactions were determined relative to that of the monitoring reaction 197Au(γ,n)196Au. To validate the experimental results, theoretical predictions were also made using the computer code TALYS 1.9. The current integrated cross-sections of the 197Au(γ,xn)197-xAu reactions with 60 MeV bremsstrahlung end point energy are measured for the first time.
