Experimental constraints on the ⁷³Zn(n, γ)⁷⁴Zn reaction rate

RADIOACTIVITY ⁷⁴Cu(β^-)[⁷⁴Cu ions from Be(⁸⁶Kr, X), E=140 MeV/nucleon reaction and using A1900 separator at NSCL-MSU facility]; measured β particles, Eγ, Iγ, βγ-coin, half-life of ⁷⁴Cu decay using the Summing NaI detector for total absorption spectroscopy (TAS); deduced nuclear level density (NLD), and γ strength function (γSF) using the β-Oslo method, distribution of spins for levels in ⁷⁴Zn around S(n). Comparison with previous experimental results, and with theoretical calculations using TALYS code. Results used to deduce σ for ⁷³Zn(n, γ) reaction.

NUCLEAR REACTIONS ⁷³Zn(n, γ), E=0.01-1 MeV; deduced σ(E), and astrophysical reaction rates using the experimental NLD and γSF. Comparison with Hauser-Feshbach statistical model calculations using TALYS code.
