The W-187 isotope has a half-life time of 23.9 hours and provides radiologically potentially beneficial β-radiation of 0.6 MeV and 1.3 MeV of kinetic energy. After confirming the neutron capture cross section of 186 W (σ 0 = 37.8 ± 1.8 b for thermal and I 0 = 476 ± 25 b for resonance integrals with σ 0 /I 0 = 12.6 ± 0.4) in two short irradiations, longer irradiations (1–10 d) were performed to obtain a value of 6.5 ± 0.8 b for the σ 0 of 187 W, which is lower than the adopted value by a Use of 182 Hf-182 W, 187 Re-187 Os, 190 Pt-186 Os, and 146,147 Sm-142,143 Nd isotope systems to study mantle heterogeneities resulting from primordial planetary differentiation processes and possible interactions between the Earth's core and lowermost mantle. Targeted rocks include ancient komatiites and modern ocean island basalts. to the W 187 was the long-lived electron-capture isotope, W 181. All data were taken early in the decay of each source in order to eliminate interference from W 181 . The prompt coincidence measurements employed a fast-slow coincidence circuit with a resolving time of 35 ns.
