We demonstrate that the recent measurement of the cross section line shapes of e(+) e(-)-> x(c0)(omega) can be be naturally explained by the molecular picture for Y(4260) where the Y(4260) is treated as a hadronic molecule dominated by (D) over barD(1)(2420) + c.c. This result is consistent with properties extracted for Y(4260) as the (D) over tildeD(1)(2420) + c. c. molecular state in other reactions such as e(+) e(-) -> J/psi pi pi, h(c)pi pi, (D) over barD* pi + c.c., and gamma X(3872).
