Abstract
The pi(0) momentum dependence of the decay eta --> pi(+)pi(-)pi(0) has been measured with the Crystal Barrel detector. The analysis is based on 3230 events. The results of this independent measurement are compa red to new chiral perturbation theory calculations and previous measur ements. (C) 1998 Elsevier Science B.V.
