We find clear gamma(10860) and gamma(11020) peaks with little or no continuum contribution. We study the resonant substructure of the gamma(11020) -> h(b)(nP)pi(+)pi(_) transitions and find evidence that they proceed entirely via the intermediate isovector states Z(b)(10610) and Z(b)(10650). The relative fraction of these states is loosely constrained by the current data: The hypothesis that only Z(b)(10610) is produced is excluded at the level of 3.3 standard deviations, while the hypothesis that only Z(b)(10650) is produced is not excluded at a significant level.text::journal::journal article::research article
