Photoneutron cross sections for Ni isotopes: Toward understanding (n, γ) cross sections relevant to weak s-process nucleosynthesis

NUCLEAR REACTIONS ^58,60,61,64Ni(γ, n), E=8.00-22.02 MeV; measured E(n), I(n), σ(E) using ³He proportional counters for neutrons and LaBr3(Ce) detector for γ-flux at NewSUBARU synchrotron radiation facility; deduced γ-ray strength functions (γSF); compared σ(E) with previous experimental data, and with TALYS predictions. ^58,60,63,64(n, γ), E=0.01-10 MeV; calculated radiative σ(E) and Maxwellian averaged σ (MACS) in terms of the experimentally constrained γ-ray strength functions from the Hartree-Fock-Bogolyubov plus quasiparticle-random-phase approximation (HFB+QRPA) based on the Gogny D1M interaction for E1 and M1 components, supplemented with the M1 upbend. Relevance to the s-process nucleosynthesis, and radioactive nuclei at the s-process branching points.

Photoneutron cross-section measurements in the ²⁰⁹Bi (γ, xn) reaction with a new method of direct neutron-multiplicity sorting

NUCLEAR REACTIONS ²⁰⁹Bi(γ, n), (γ, np), (γ, 2n), (γ, 2np), (γ, 3n), (γ, 3np), (γ, 4n), (γ, 4np), E=threshold-40 MeV; measured E(n), I(n), photoneutron σ(E) using quasimonochromatic laser Compton-scattering (LCS) γ-ray beams at the NewSUBARU synchrotron radiation facility at the University of Hyogo, and novel technique of direct neutron-multiplicity sorting method. Comparison with previous experimental data from Livermore and Saclay, and with bremsstrahlung data, and with theoretical calculations using the TALYS reaction code. Comparison with Hartree-Fock Bogoliubov plus quasiparticle random phase approximation (HFB+QRPA) with Gogny D1M interaction for both E1 and M1 components of the GDR. Discussed threshold behavior of photoneutron emission in terms of average neutron kinetic energy.
