We study the decays , , , , , , with , from the perspective of the being a molecular state made from the interaction of the , and components. We consider both the external and internal emission decay mechanisms and find an explanation for the and production rates, based on the mass difference of the charged and neutral components. We also find that the internal and external emission mechanisms add constructively in the , reactions, while they add destructively in the case of , reactions. This feature explains the decay widths of the present measurements and allows us to make predictions for the unmeasured modes of and . The future measurement of these decay modes will help us get a better perspective on the nature of the and the mechanisms present in production reactions of that state.
