Total neutron capture cross section measurements of the separated isotope of /sup 64//sub 30/Zn have been made in the energy interval of 2.5--900 keV. These were made using time-of-flight techniques and a total energy ..gamma..-ray detector system with a nominal resolution of about 0.12 ns/m. Resonance energies and capture areas were determined for 191 resonances up to 131 keV. Values of the radiation widths and neutron widths for many resonances have been determined making use of the results available from transmission measurements. From these results mean values of 726=(plus-or-minus60) meV for s-wave and 272=(plus-or-minus30) meV for p-wave resonances have been determined. A value for the p-wave strength function S/sub 1/0.75=(plus-or-minus0.08) x 10/sup -4/ eV/sup -1/2/ was obtained for neutron energy up to 130 keV. Bayes' theorem for conditional probability was used to identify d-wave levels and from these resonances a lower limiting value for d-wave strength function S/sub 2/0.78=(plus-or-minus0.12) x 10/sup -4/ eV/sup -1/2/ was obtained. The values for the p-wave mean level spacing for all resonances observed up to 130 keV, and after elimination of d-wave resonances, were found to be (0.68 +- 0.04) and (1.10 +- 0.07) keV, respectively. An analysis of the linear correlation coefficient (rho) between GAMMA/sup 0//sub n/ and GAMMA/sub ..gamma../ gave a value of (0.47 +- 0.08) at a confidence level of 99.7%.
