摘要：

Using the CLEO II detector at CESR, we measure the eta' energy spectra in Y(1S) decays that we compare with models of the eta'g*g form factor. This form factor, especially at large eta' energies, may provide an explanation of the large rate for B-->X(s)eta'. Our data do not support a large anomalous coupling at higher q(2) and thus the large eta' rate remains a mystery, possibly requiring a non-standard-model explanation.
