The L$σ$M is used as an appropriate framework for describing the pole effects of the $a_0(980)$ scalar resonance. As a result, a better agreement with present available data is achieved for the higher part of the $π^0η$ invariant mass spectrum. For the branching ratio, a value of $B(ϕ\toπ^0ηγ)=(0.75$--$0.95)\times 10^{-4}$ is found.10 pages, 2 figures.
