A local derivative coupling model is used to study the φ′→ππ and other dipionic decays of φ and φ″, as an alternative to the ε-model. The results obtained are quite satisfactory. We findt hat the existence of the ε-resonance is not essential in order to understand the dipionic decays of the psions at the present level of experimental data available. © 1978 Indian Academy of Sciences.
