Neutron-radiative-capture cross sections have been measured at various energies from 30-220 keV using a new "total-energy-detector" technique of high sensitivity, applicable to small samples of separated stable isotopes. Samples studied are: V, Fe, Ni, ⁸⁶Sr, ⁸⁷Sr, Y, Nb, Rh, Ag, ¹²²Te, ¹²³Te, ¹²⁴Te, ¹²⁵Te, ¹²⁶Te, ¹²⁸Te, ¹³⁰Te, I, Eu, ¹⁷⁵Lu, ¹⁷⁶Lu, W, Au, ²⁰⁴Pb, and ²⁰⁸Pb. The odd-odd isotope ¹⁷⁶Lu shows a substantially higher cross section than those of neighboring odd-even and even-odd nuclei. The results for europium (2 b near 65 keV) emphasize the peak expected from previous studies of systematics. The Sr and Te isotopic results strongly confirm the predictions of s-process stellar nucleosynthesis.
