The 5.8 pb-1 of data collected by the CMD-2 Collaboration in the energy range 1.05-1.38 GeV have been used to study energy dependence of the processes e+e- → π+π-2π0 and e+e- → 2π+2π-. Analysis of the differential distributions demonstrates the dominance of the a1(1260)π and ωπ intermediate states. Upper limits for the contributions of other possible states are also obtained. © 1999 Published by Elsevier Science B.V. All rights reserved.
