摘要：

We study the pipi spectrum in UPSILON(3S) --> UPSILON(1S)pipi decay using the most general matrix element in the lowest order in the pion momentum expansion. We find a good fit to the pipi spectrum, and predict various angular distributions of decay products of UPSILON(3S), all of which can be tested by current experiments.
