engCakirli, R. B.Blaum, K.Casten, R. F.Confirmation and extension of a mini-valence Wigner-like energy in Sm, Gd, and Dyinfo:eu-repo/classification/ddc/530An earlier study revealed an unexpected enhancement in valence proton-neutron interaction strengths in certain heavy deformed even-even nuclei with equal numbers of valence protons and valence neutrons. The paper reports on an extension of those results to the entire span of deformed nuclei from Sm to W using mass data taken in the interim.Physical review / C 111(1), 014305 (2025). doi:10.1103/PhysRevC.111.014305info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionInst.2025info:eu-repo/semantics/openAccessDEhttps://repository.gsi.de/record/364107https://repository.gsi.de/search?p=id:%22GSI-2026-00286%22Researchersinfo:eu-repo/semantics/altIdentifier/wos/WOS:001399124000002info:eu-repo/semantics/altIdentifier/issn/2470-0002info:eu-repo/semantics/altIdentifier/issn/2469-9993info:eu-repo/semantics/altIdentifier/doi/10.1103/PhysRevC.111.014305info:eu-repo/semantics/altIdentifier/issn/0556-2813info:eu-repo/semantics/altIdentifier/issn/1538-4497info:eu-repo/semantics/altIdentifier/issn/2469-9985info:eu-repo/semantics/altIdentifier/issn/1089-490Xinfo:eu-repo/semantics/altIdentifier/doi/10.15120/GSI-2026-00286
