Abstract: (Springer)

We study

e^ +e^ -\to \tilde e^ +\tilde e^ -

together with

\tilde e^ \pm

decay emphasizing the importance of neutralino mixing in thet-channel at energies above theZ0 resonance. This illustrated in three different mixing scenarios. Formulae fore^ +e^ -\to \bar \tilde v_e \tilde v_e are also given.
