Measurement of electro-magnetic radiation at RHIC-PHENIX

Abstract

Recent results on direct photons and dileptons from the PHENIX experiment opened up a possibility of landscaping electro-magnetic radiation over various kinetic energies in heavy ion collisions. Results on direct photon measurement in Au+Au collisions at $\sqrt{s_{NN}}$=200GeV are discussed from the point of view of structure function and isospin effect. It is supported by the first measurement of direct photons at $\sqrt{s_{NN}}$=62.4GeV in the same collisional system.
