The 72Ge(n,α)69mZn, 74Ge(n,α)71mZn, 76Ge(n,2n)75g+mGe and 191Ir(n,2n)190Irg+m1 and 191Ir(n,2n)190Irm2 reaction cross sections were measured from 9.6 to 11.4 MeV relative to the 27Al(n,α)24Na reference reaction via the activation method. The quasi-monoenergetic neutron beams were produced via the 2H(d,n)3He reaction at the 5 MV VdG Tandem T11/25 accelerator of NCSR "Demokritos". Statistical model calculations using the codes STAPRE-F and EMPIRE (version 2.19) and taking into account pre-equilibrium emission were performed on the data measured in this work as well as on data reported in literature.
