Abstract
A complete tree-level calculation of the reaction e+ e- --> e+nu(e)tbB AR (e-nu(e)tbBAR) in the electroweak standard theory in the LEP200 ene rgy range is presented. For top quark masses in the range 130 to 190 G eV the cross sections are found to be in the order of 10(-5) to 10(-6) pb. Therefore, the number of single top quark events is expected to b e negligible even with an integrated luminosity of L = 500 pb-1. It is further demonstrated that the Weizsacker-Williams approximation appro aches the accurate cross section calculations reasonably well.
