Abstract
The 5.8 pb(-1) of data collected by the CMD-2 Collaboration in the energy r ange 1.05-1.38 GeV have been used to study energy dependence of the process es e(+)e(-)- --> pi(+)pi(-)2 pi(0) and e(+)e(-) --> 2 pi(+)2 pi(-). Analysi s of the differential distributions demonstrates the dominance of the a(1)( 1260)pi and omega pi intermediate states. Upper limits for the contribution s of other possible states are also obtained. (C) 1999 Published by Elsevie r Science B.V. All rights reserved.
