Jefferson Lab's experiment E04-005, the largest integrated luminosity real photon CLAS experiment to date, provided a large sample of leptonic data allowing for studies of rho-omega interference in the dileptonic decay channel, as well as charge radius and comparative branching ratio studies of the eta and eta-prime through the Dalitz decay channel. An experimental study of the rho-omega interference provides valuable input for theoretical models and calculations in addition to establishing a comparative basis for medium modification studies of vector mesons photoproduced off of heavier targets. The total statistics collected for the eta Dalitz exceed the world's published statistics by an order of magnitude, while the eta-prime Dalitz decay is observed and measured for the first time.
