• Interpreting a narrow resonance with mass 1.44 GeV observed in radiative φ-decay as a pseudoscalar glueball, we analyze the decay process φ→γ+ glueball from the diagramatic point of view. Our aim is to derive the effective vertex constant for the glueball coupling with two gluons which will occupy an important position in the quantum chromodynamics. The consequence from our analysis leads us to conclude that this constant has its value in vicinity of 10^<-2> 〜 10^<-1> GeV^<-1>.
