Abstract
The ⁷²Ge(n,α)^69mZn, ⁷⁴Ge(n,α)^71mZn, ⁷⁶Ge(n,2n)^75g+mGe and ¹⁹¹Ir(n,2n)¹⁹⁰Ir_g+m1 and ¹⁹¹Ir(n,2n)¹⁹⁰I_rm2 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.
