The product branching fractions of (psi 3686) -> gamma chi(c1), chi(c1) -> gamma J/psi (3686) -> gamma chi(c2), chi(c2) -> gamma J/psi and the branching fractions of chi(c1) -> gamma J/psi and chi(c2) -> gamma J/psi are also presented.eninfo:eu-repo/semantics/openAccessArticle2-s2.0-8506520165210.1103/PhysRevD.96.032001Q1Q1WOS:000407552600001
