Using the known scattering data, we recover the potential in the Dirac equation. The Gel’fand-Levitan-Marchenko integral equation is derived and potential is explicitly obtained for the case of a primary star graph.</p></abstract><kwd-group xml:lang="en"><kwd>quantum graph</kwd><kwd>inverse scattering problem</kwd><kwd>Dirac equation</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Gnutzmann S. and Smilansky U.
