Experimental results on the Dalitz decay of P(π0, η, η’)->e+ e- γ pseudoscalar mesons produced in the photoproduction reaction γ + p -> P(π0, η,η’) + p on a Hydrogen target with CLAS are presented for the first time. The total statistics collected for η Dalitz decay exceeds the world’s published statistics by an order of magnitude, while the Dalitz decay of η’->e+ e- γ is observed and measured for the first time. The data obtained will allow for an update on already measured branching ratios and provide branching ratio of η’ in this channel. Current status of analysis and future prospects are discussed.
