The cross sections of nuclear reactions induced by deuteron particles on natural germanium were investigated by using the stacked target technique, activation method and standard high resolution gamma spectrometry. Targets were natural germanium, vacuum evaporated onto 25 micron thick polyimide (kapton) foils with nominal thickness of about 2 mu m. The stack was composed of 26 kapton-Ge-Ge-kapton sandwich targets foils and 24 aluminum and 25 titanium foils with nominal thickness of 50 and 11 lam respectively. The Al foils served as monitors and at the same time as energy degraders in the high energy part of the stack. Ti foils were included in the stack to monitor the beam parameters in the low energy region. The irradiation was done with 50 MeV deuteron particles with a beam current of about 50 nA for about 1 h. Activation cross sections were determined for production of the As-70,As-71,As-72,As-73,As-74,As-76, Ge-69,Ge-75,Ge-77 and Ga-66,Ga-67,Ga-73 radionuclides. The deduced experimental cross sections were compared to the results of theoretical calculations taken from the TENDL-2013 data library based on the TALYS computer code. A comparison was made with available experimental data measured earlier. Thick target yields were deduced from the experimental cross sections and were compared with the data published before. The possible production routes of arsenic radioisotopes are discussed. (C) 2014 Elsevier B.V. All rights reserved.
