Summary

Cross sections, averaged over a 235U fission neutron spectrum, of some threshold reactions induced on zinc after short irradiations, have been measured. The studied reactions and the corresponding values are: 64Zn(n, p) 64Cu, (37.4 ± 1.4) mb; 64Zn(n, 2n) 63Zn, (23.4 ± 2.0) μb; 66Zn(n, p) 66Cu, (0.775 ± 0.079) mb; 68Zn(n, p)68mCu, (5.32 ± 0.65) μb; and 68Zn(n, α) 65Ni, (52.1 ± 2.3) μb, all referred to the cross section of the 27Al(n, p) 27Mg standard reaction, (3.84 ± 0.18) mb. Working values for the resonance integrals of the reactions 70Zn(n, γ) 71Zn and 70Zn(n, γ)71mZn, referred to the tabulated value for the resonance integral of the 68Zn(n, γ)69mZn reaction, (0.24 ± 0.03) b, were also obtained. The results were (0.1350 ± 0.0093) b and (0.157 ± 0.029) b, respectively.
