Abstract
A newly developed facility at the 3 MV Tandem Accelerator at Dhaka for measurement of proton induced reaction cross sections in the energy region below 5 MeV is outlined and tests for the beam characterization are described. The results were validated by comparison with the well-known excitation function of the Ni-64(p, n)Cu-64 reaction. Excitation functions of the reactions Ni-nat(p, x)Cu-60,Cu-61, Ni-nat(p, x)Co-55,Co-57,Co-58m+g and Ni-nat(p, x)Ni-57 were also measured from threshold to 16 MeV using the stacked-foil technique, whereby irradiations were performed with 5 MeV protons available at the Tandem Accelerator and 16.7 MeV protons at the BC 1710 cyclotron at Julich, Germany. The radioactivity was measured using HPGe gamma-ray detectors. A few results are new, the others strengthen the database. In particular, the results of the reaction Ni-nat(p, x)Cu-61 below 3 MeV could serve as beam monitor.
