Experimental cross-section data for (n,xn) reactions with x higher than four and neutron energies over similar to 30 MeV are very scarce. We performed seven successful (n, xn) cross-section measurements in two campaigns exploiting the quasi-monoenergetic neutron source at The Svedberg Laboratory in Uppsala, Sweden. Neutron energies from the Li-7(p,n)Be-7 based source were in the region 22 to 94 MeV. We carried out additional five irradiations with neutron energies from 17 up to 34 MeV using the quasi-monoenergetic neutron source of the Nuclear Physics Institute in Rez. We have irradiated Al, Au, Bi, I, In, Ta and Y materials in the form of thin foils. We observed good agreement with the few existing experimental data about corresponding cross-sections in EXFOR database and also with the calculations performed in deterministic code TALYS.
