In this work, the cross sections of the neutron induced reactions 70Ge(n,2n)69Ge, 76Ge(n,2n)75Ge, 73Ge(n,p)73Ga, 72Ge(n,p)72Ga, 73Ge(n,d/np)72Ga, 74Ge(n,d/np)73Ga, 74Ge(n,α)71mZn, 72Ge(n,α)69mZn, 73Ge(n,nα)69mZn have been measured in the energy range between 16.4 and 18.9 MeV via the activation technique with respect to the 27Al(n,α)24Na reference reaction. Most of the existing experimental datasets found in literature for these reactions, were obtained with the use of a natGe target. In this case however, the residual nucleus produced from some reaction channels, could also be produced from neutron induced reactions in neighboring isotopes that exist in the natGe in their natural abundance, acting as a contamination to the measured yield of the reaction of interest. This parasitic contribution should then be subtracted, based on theoretical calculations that bear their own uncertainties. Isotopically enriched targets on the other hand, do not suffer from such contaminations, leading to more accurate experimental cross section results. In this work, five highly enriched targets have been used that helped in the determination of accurate cross section data, especially in the case of the73Ge(n,d/np)72Ga, 74Ge(n,d/np)73Ga and 73Ge(n,nα)69mZn challenging reactions, that will be presented in detail in this manuscript. The experiments were carried out at the 5.5 MV Tandem Van de Graaff accelerator of N.C.S.R. “Demokritos”, implementing the 3H(d,n)4He reaction for the production of the quasi-monoenergetic neutron beams.

“…The measurements of the (n, 2n), (n, p), (n, α) and (n, f) cross sections have been the focus of the successful research program. The neutron facility of TAL, which can produce monoenergetic neutron beams with fluxes of ≈ 10 5 -10 6 ncm −2 s −1 in the energy ranges of thermal to 450 keV, 4 MeV to 11.5 MeV, and 16 MeV to 20.5 MeV by using the 7 Li(p,n), 2 H(d, n) and 3 H(d, n) reactions [146], [147] , is a key tool in the implementation of this program. The laboratory has also taken part in a coordinated research program on proton-induced gamma-ray emission (PIGE) technique improvement, evaluating existing PIGE data, and measuring…”

Small-scale facilities play a significant role in the landscape of nuclear physics research in Europe. They address a wide range of fundamental questions and are essential for teaching and training personnel in accelerator technology and science, providing them with diverse skill sets, complementary to large projects. The current status and perspectives of nuclear physics research at small-scale facilities in Europe will be given.

Τhe 70Ge(n,2n)69Ge, 72Ge(n,a)69mZn, 72Ge(n,p)72Ga and 73Ge(n,p)73Ga reactions have been measured by means of the activation technique at neutron energy 17.9 MeV. The quasimonoenergetic neutron beam was produced via the 2H(d,n)3He reaction at the 5.5 MV Tandem Van de Graaff accelerator of NCSR “Demokritos.” Isotopically highly enriched targets of 70Ge, 72Ge and 73Ge, provided by the nTOF collaboration at CERN, have been used, thus allowing accurate cross section measurements since no corrections are needed to compensate for the parasitic reactions from neighboring isotopes that exist in the case of using natural Ge target. The cross section has been deduced with respect to the 27Al(n,α)24Na reference reaction.
