Study of $Delta(1232)$ isobar electroproduction at VEPP-2M $e^+e^-$ collider

Results from the Spherical Nonmagnetic Detector (SND) on $Delta (1232)$ isobar electroproduction in the collisions of beam electrons (positrons) and residual gas nuclei in the VEPP-2M $e^+e^-$ collider are presented. On the basis of the obtained data the expected counting rate of this process in future high luminosity $e^+e^-$ colliders (~$phi$-, $c$-$tau$- and $b$-factories) was estimated.
