This long-standing discrepancy, referred to as the gallium anomaly, has posed a significant challenge to our understanding of both experimental methods and theoretical predictions. In this Letter, we revisit the theoretical calculation of the neutrino capture cross section by moving beyond the standard treatment of the leptonic wave functions, revealing limitations in the commonly used factorization approach based on the detailed balance principle. Incorporating phenomenologically constrained Gamow-Teller transition densities, able to correctly reproduce the precisely measured half-life of\n                    <k:math xmlns:k=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" display=\"inline\">\n                      <k:mrow>\n                        <k:mmultiscripts>\n                          <k:mrow>\n                            <k:mi>Ge<\/k:mi>\n                          <\/k:mrow>\n                          <k:mprescripts\/>\n                          <k:none\/>\n                          <k:mrow>\n                            <k:mn>71<\/k:mn>\n                          <\/k:mrow>\n                        <\/k:mmultiscripts>\n                      <\/k:mrow>\n                    <\/k:math>\n                    , we find that the revised cross section can be significantly reduced, potentially resolving the gallium anomaly without invoking new physics.\n                  <\/jats:p>","DOI":"10.1103\/5pvf-mcr1","type":"journal-article","created":{"date-parts":[[2026,7,31]],"date-time":"2026-07-31T12:52:55Z","timestamp":1785502375000},"update-policy":"https:\/\/doi.org\/10.1103\/crossmark-policy","source":"Crossref","is-referenced-by-count":2,"title":["Possible Solution to the Gallium Anomaly Moving beyond the Leptonic Wave-Function Factorization"],"prefix":"10.1103","volume":"137","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3974-1995","authenticated-orcid":true,"given":"M.","family":"Cadeddu","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/03paz5966","id-type":"ROR","asserted-by":"publisher"}],"name":"Istituto Nazionale di Fisica Nucleare (INFN), Sezione di Cagliari"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6515-5850","authenticated-orcid":true,"given":"N.","family":"Cargioli","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/03paz5966","id-type":"ROR","asserted-by":"publisher"}],"name":"Istituto Nazionale di Fisica Nucleare (INFN), Sezione di Cagliari"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2571-5067","authenticated-orcid":true,"given":"F.","family":"Dordei","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/03paz5966","id-type":"ROR","asserted-by":"publisher"}],"name":"Istituto Nazionale di Fisica Nucleare (INFN), Sezione di Cagliari"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-1698-3710","authenticated-orcid":true,"given":"L.","family":"Ferro","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/003109y17","id-type":"ROR","asserted-by":"publisher"}],"name":"Universit\u00e0 degli Studi di Cagliari"},{"id":[{"id":"https:\/\/ror.org\/03paz5966","id-type":"ROR","asserted-by":"publisher"}],"name":"Istituto Nazionale di Fisica Nucleare (INFN), Sezione di Cagliari"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2281-4788","authenticated-orcid":true,"given":"C.","family":"Giunti","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/01vj6ck58","id-type":"ROR","asserted-by":"publisher"}],"name":"Istituto Nazionale di Fisica Nucleare (INFN)"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-1854-0339","authenticated-orcid":true,"given":"M.","family":"Pitzalis","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/003109y17","id-type":"ROR","asserted-by":"publisher"}],"name":"Universit\u00e0 degli Studi di Cagliari"},{"id":[{"id":"https:\/\/ror.org\/03paz5966","id-type":"ROR","asserted-by":"publisher"}],"name":"Istituto Nazionale di Fisica Nucleare (INFN), Sezione di Cagliari"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"16","published-online":{"date-parts":[[2026,9,24]]},"reference":[{"key":"5pvf-mcr1Cc1R1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ppnp.2023.104082","type":"journal-article"},{"key":"5pvf-mcr1Cc2R1","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevC.83.065504","type":"journal-article"},{"key":"5pvf-mcr1Cc3R1","doi-asserted-by":"publisher","DOI":"10.1016\/0370-2693(92)91521-A","type":"journal-article"},{"key":"5pvf-mcr1Cc4R1","doi-asserted-by":"publisher","DOI":"10.1016\/S0370-2693(98)01579-2","type":"journal-article"},{"key":"5pvf-mcr1Cc5R1","doi-asserted-by":"publisher","DOI":"10.1016\/j.physletb.2010.01.030","type":"journal-article"},{"key":"5pvf-mcr1Cc6R1","doi-asserted-by":"publisher","DOI":"10.1016\/j.physletb.2005.04.068","type":"journal-article"},{"key":"5pvf-mcr1Cc7R1","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevC.80.015807","type":"journal-article"},{"key":"5pvf-mcr1Cc8R1","doi-asserted-by":"publisher","DOI":"10.1142\/9789811204296_0002","type":"book","volume-title":"Solar Neutrinos","author":"V.\u2009N.
