Abstract (data abstract)
Novosibirsk-VEPP-2M Collider. Measurement of the cross section for the process E+ E- --& gt; MU+ MU- in the energy region 980 and 1040 to 1380 MeV. The data were collected from 1995 to 2000 and have an integrated luminosity of 6.4 pb-1. The normalization is to the luminosity using E+ E- --& gt; E+ E- and E+ E- --& gt; GAMMA GAMMA data.
