摘要：

Assuming the QCD multipole expansion is applicable to hadronic transitions of UPSILON(3S) into lower level bottomonia, we consider the possibility that UPSILON(3S) has a D-wave component. This assumption leads to a natural explanation of the pipi spectrum in UPSILON(3S) --> T(1S) pipi. The consequences of this assumption on other hadronic and radiative transitions of UPSILON(3S) are also discussed in the same context.
