EPJ Web of Conferences
New measurement of the e+e−→ nn̅cross section based on the data set recorded in 2017 with the SND detector at the VEPP-2000 e+e− collider is presented.Inthe energyrangefromthe thresholdupto2GeVthe cross section is almost flat. Its average value is 0.5 nb. The polar angle distribution indicates dominanceof the magnetic formfactor GM .
