Deducing primary γ-ray intensities and the dipole strength function in ⁹⁴Mo via radiative proton capture

NUCLEAR REACTIONS ⁹³Nb(p, γ)⁹⁴Mo, E=3.0, 3.5 MeV; ⁹⁴Mo(p, p')⁹⁴Mo, E=13.5 MeV; measured Eγ, Iγ, pγ- and γγ-coin using HORUS γ-ray spectrometer for γ detection and SONIC array for scattered protons at the FN-Tandem accelerator of University of Cologne. ⁹⁴Mo; deduced levels, J, π, γ-branching ratios, primary γ rays from two-step cascade (TSC) spectra, partial cross-sections at E(p)=3.0 and 3.5 MeV, E1 and M1 strength functions, absolute γ-strength function (γSF). Systematics of γ strength functions in ⁹²Mo, ⁹⁴Mo and ⁹⁶Mo. Comparison of γ strength functions with experimental results using the Oslo method and photoinduced experiments as well as with recent theoretical quasiparticle random-phase approximation (QRPA) calculations. Relevance to nucleosynthesis of heavy nuclei in the slow and rapid neutron capture processes.
