Observation of this dynamic phase transition would indicate distinct burn properties and indicate an implosion's robustness. A technique for diagnosing the presence of thermal runaway from measurements of nuclear reaction history is presented. The technique is based on taking the logarithmic derivative of the nuclear reaction history, called the\n                    <a:math xmlns:a=\"http:\/\/www.w3.org\/1998\/Math\/MathML\">\n                      <a:mi>\u03b1<\/a:mi>\n                    <\/a:math>\n                    curve, and allowing a mathematical decoupling of the mass, volume, and thermal reactivity in the fusion reaction rate equation.

This provides a distinct signature related to the fundamental nature of the DT fusion nuclear resonance and signifies the transition into the fusion thermal instability. Impacts of charged particle transport on the effect are also assessed and the analytical formulas are compared and found to be in agreement with radiation hydrodynamic codes.\n                  <\/jats:p>","DOI":"10.1103\/pl89-ftjd","type":"journal-article","created":{"date-parts":[[2026,2,27]],"date-time":"2026-02-27T20:20:02Z","timestamp":1772223602000},"update-policy":"https:\/\/doi.org\/10.1103\/crossmark-policy","source":"Crossref","is-referenced-by-count":3,"title":["Utilizing the deuterium-tritium fusion resonance to diagnose thermal runaway in igniting plasmas"],"prefix":"10.1103","volume":"113","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8831-2145","authenticated-orcid":true,"given":"Robert H.","family":"Dwyer","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/01e41cf67","id-type":"ROR","asserted-by":"publisher"}],"name":"Los Alamos National Laboratory"},{"id":[{"id":"https:\/\/ror.org\/022kthw22","id-type":"ROR","asserted-by":"publisher"}],"name":"University of Rochester"},{"id":[{"id":"https:\/\/ror.org\/022kthw22","id-type":"ROR","asserted-by":"publisher"}],"name":"University of Rochester"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1142-7360","authenticated-orcid":true,"given":"K.
