The mass spectrum and strong decays of the and are analyzed. Our results indicate that and are the two different resonances. The narrower seems likely a good hybrid candidate. We support the as the quarkonium. We suggest to search the isospin partner of in the channels of and in the future. The latter channel is very important for testing the hybrid scenario.
