Activation cross-section measurements for producing short-lived nuclei with 14 MeV neutrons—Ge, Pd, Yb

Activation cross sections for ⁷⁰Ge(n,p)⁷⁰Ga, ⁷⁴Ge(n,p)⁷⁴Ga, ¹⁰⁸Pd(n,p)¹⁰⁸Rh, ¹¹⁰Pd(n,α)¹⁰⁷Ru, and ¹⁷⁴Yb(n,p)¹⁷⁴Tm reactions producing short-lived nuclei with half-lives of several minutes were measured in the energy between 13.5 and 14.8 MeV using activation technique in this work. All cross-section values were relatively obtained on the basis of the standard cross section of ⁹³Nb(n,2n)^92mNb or ²⁷Al(n,α)²⁴Na, and the neutron energies were measured by the method of cross-sectional ratios for ⁹⁰Zr(n,2n)^89m+gZr to ⁹³Nb(n,2n)^92mNb reactions. Careful attention on corrections was paid to neutron irradiation and induced activities measurement. The measured results were discussed and compared with the previous works.
