We study the 
reaction where the 
excitation plays a dominant role. We consider mechanisms of external and internal emission at the quark level, hadronize the 
components into two mesons and allow these mesons to undergo final state interaction where the state is generated. While the production is the dominant term, we also find other terms in the reaction that interfere with this production mode and, through interference with it, lead to a shape of the significantly different from the one observed in other experiments, with an apparently much larger width.
