Abstract
Previous claims for the existence of vector mesons with masses in the vicinity of 1100 MeV and 1300 MeV are reconsidered in the light of rec ent developments in the analysis and interpretation of e+e- annihilati on and diffractive photoproduction data. It is shown that these states are compatible with present evidence and can be incorporated in an ex tended mixing scheme of conventional qqBAR with unconventional qqqqBAR states.
