Activation cross sections for 70Ge(n,p)70Ga70Ge(n,p)70Ga, 74Ge(n,p)74Ga74Ge(n,p)74Ga, 108Pd(n,p)108Rh108Pd(n,p)108Rh, 110Pd(n,α)107Ru110Pd(n,α)107Ru, and 174Yb(n,p)174Tm174Yb(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)92mNb93Nb(n,2n)92mNb or 27Al(n,α)24Na27Al(n,α)24Na, and the neutron energies were measured by the method of cross-sectional ratios for 90Zr(n,2n)89m+gZr90Zr(n,2n)89m+gZr to 93Nb(n,2n)92mNb93Nb(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.
