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/openAccessAstronomy & astrophysicsPhysicsRadiative decaysMonte-carloSpectroscopyArticle0004075526000012-s2.0-85065201652963Astronomy & astrophysicsPhysics, particles & fieldsCharmonium; Drift Chambers; Branching
