Experimentally constrained ^{165, 166}Ho(n, γ) rates and implications for the s process

NUCLEAR REACTIONS ¹⁶⁴Dy(α, pγ)¹⁶⁷Ho, E=26 MeV; measured Ep, Ip, Eγ, Iγ, pγ-coin. ¹⁶⁷Ho; deduced nuclear level density (NLD) and γ-ray strength function, resonance components of the GSF (Giant Dipole Resonance, Pigmy Dipole Resonance, M1 scissors resonance), upward scissor resonance strength. ^165,166Ho(n, γ), E=0.001-10 MeV; calculated σ(E) using obtained NLD and GSF (for ¹⁶⁷Ho from present work, for ¹⁶⁶Ho - from 2023PO02), Maxwellian-averaged σ(E) MACS (kT<105 keV). Oslo method type of analysis. Comparison with other experimental data and TALYS calculations. Comparison of obtained MACS with JINA REACLIB, BRUSLIB and KADONIS data. AGB nucleosynthesis predictions with STARERVOL code using obtained MACS. Oslo SCintillator ARray (OSCAR) and the Silicon Ring (SiRi) detector arrays at MC-35 Scanditronix cyclotron.
