New experimental constraint on the ¹⁸⁵W(n, γ)¹⁸⁶W cross section

NUCLEAR REACTIONS ^182,183,184W(γ, n), E=6.5-13 MeV; measured In, En; deduced σ(E), γ-ray strength function (GSF). ¹⁸⁶W(α, α'γ), E=30 MeV; measured Eα, Iα, Eγ, Iγ, αγ-coin; deduced nuclear level density (NLD), γ-ray strength function (GSF). ¹⁸⁵W(n, γ), T=0.5-1.1 GK; calculated Maxwellian averaged σ(E) (MACS), reaction rate (stellar reactivity), compared with experimental results, and recommended σ in compilations by Bao et al. Comparison to other experimental data, TALYS calculations and KADONIS-1.0 data. Photoneutron reactions were measured with quasi-monochromatic photon beam at NewSubaru synchrotron radiation facility using 4π detector consisting of 20 ³He proportional counters. Experiment on inelastic α-scattering was performed at the Oslo Cyclotron Laboratory (OCL) using CACTUS NaI(Tl) scintillator γ-ray detector array, the Silicon Ring (SiRi) detector array and beam from MC-35 Scanditronix cyclotron.
