The a-daughter nuclear interaction potentials are obtained from the double folding model, where the effective nucleon-nucleon (NN) interactions are obtained from relativistic mean field theory Lagrangian (R3Y). In addition to using R3Y NN interactions containing only linear sigma, omega, and rho mesons (R3Y-HS), R3Y parametrizations containing non-linear terms (NL2 and NL-SH) are also employed. In fact, they are found to give better descriptions of the alpha-decay half-lives than R3Y-HS. Moreover, two empirical formulas are employed in the study. They have been included to further test the accuracy of the R3Y models. (C) 2021 Elsevier B.V. All rights reserved.

The experiment was performed at the National Superconducting Cyclotron Laboratory at Michigan State University using the Summing NaI(Tl) (SuN) detector. The Cu isotopes are good candidates to probe the single-particle structure in the region because they have one proton outside the Z = 28 shell. Comparing the beta-decay intensity distributions in the daughter Zn isotopes to the theoretical predictions provides a stringent test of the calculations. The nuclei in this region are also identified as playing an important role in the astrophysical r-process. The measured beta-decay intensity distributions provide essential nuclear physics inputs required to better understand heavy element nucleosynthesis. (c) 2021 Elsevier B.V. All rights reserved.
