Abstract：
Cross sections for ⁷⁰Ge(n,2n)⁶⁹Ge,⁷⁶Ge(n,2n)⁷⁵Ge, ⁷⁰Ge(n,p)⁷⁰Ga,⁷²Ge(n,p)⁷²Ga,⁷³Ge(n,p)⁷³Ga, ⁷²Ge(n,α)^69mZn and ⁷⁴Ge(n,α)^71mZn reactions were measured at the neutron energies from 13.5 to 14.6MeV using activation technique and γ-ray spectrometry. The neutron fluences was determined using the monitor reaction ⁹³Nb(n, 2n) ^92mNb and the neutron energies were measured by the method of cross section ratios for ⁹⁰Zr(n,2n)^89m+gZr to ⁹³Nb(n,2n)^92mNb reaction. The results of present work were compared with data published previously.
