The relative abundances of the isotopes of Zr in the S stars R Cyg and V Cnc are calculated by determining isotopic splitting at the head of the 1Pi - 1Sigma (0, 1) band of ZrO in spectra obtained at resolution 30 pm on hypersensitized 127-O4 plates with a Varo tube on the 51-cm camera at the Coude focus of the 3-m telescope at Lick Observatory. The data reduction techniques and the fit to the model synthetic spectra of Kurucz (1970) are described, and the ratio (Zr-90):(Zr-91):(Zr-92):(Zr-93):(Zr-94):(Zr-96) is given as 47:10:17:6:20:00 percent. The presence of the long-lived unstable isotope Zr-93 is interpreted as evidence for recent nucleosynthesis, and the abundances found are shown to be consistent with s-process nucleosynthesis.
