Abstract (data abstract)
NOVOSIBIRSK-VEPP-2M Collider. Measurement of the cross sections for the 4 PI processes E+ E- --& gt; PI+ PI- 2PI0 and E+ E- --& gt; 2PI+ 2PI- in the energy range 1.05 to 1.38 GeV. The data were recorded in 1997 at the VEPP-2M collider and have an integrated luminosity of 5.8 pb-1.. Numerical values supplied by S. Eidelman.
