Observation of hc Radiative Decay hc → γη' and Evidence for hc → γη

A search for radiative decays of the P-wave spin singlet charmonium resonance hc is performed based on 4.48×108 ψ' events collected with the BESIII detector operating at the BEPCII storage ring. Events of the reaction channels hc→γη' and γη are observed with a statistical significance of 8...
