Low noise, high resolution Reticon and Digicon spectra have been subjected to an abundance analysis for the Rb to Nb series of elements in Zeta Cap, relative to the G-giant standard, Epsilon Vir. The analysis has determined an Nb abundance that is consistent with the complete decay of Zr-93 to Nb-93, so that more than 3 million years have elapsed since the principal phases of s-processing. The Rb abundance suggests a neutron density of about 10 million/cu cm at the s-process site, at the close of s-processing. 26 references.
