Resumen

Recent data on the η′→ηππ rate are shown to provide valuable information concerning the ratio between the δη′π and δηπ coupling constants. This is consistent with an ordinary (qq) interpretation for the δ-meson and makes its alternative interpretation as a qqqq meson rather unlikely. © 1980.
