title: Neutron capture cross sections of70Zn and the decay of71mZn.
abstract: Radiative neutron capture was studied in the70Zn(n,γ)71m,gZn reaction in order to determine the thermal neutron capture cross sections for the reactions. The resonance integrals were also measured to facilitate corrections for the epithermal neutron component. In addition, cross sections for the64Zn(n,γ)65Zn and68Zn(n,γ)69mZn reactions were determined. Through high-resolution γ-ray spectrometry in the71mZn decay, a new set of γ-ray energies and intensities was obtained of roughly an order of magnitude greater precision than the previous set, and several transitions new to the decay scheme are proposed. The implications for the properties of the levels of71Ga are discussed. More precise values of the decay half-lives for69mZn,71gZn, and71mZn have been determined.
