[en] We study the production process e⁺e^- → χ₁⁰χ₂⁰ and the subsequent decay χ₂⁰ → χ₁⁰l⁺l^- with polarized e⁺ and e^- beams, including the spin correlations between production and decay. We work out the advantages of polarizing both beams. We study in detail the angular distribution and the forward-backward asymmetry of the decay lepton as well as the opening angle distribution between the decay leptons. We investigate the dependence on the masses of e_L and eR and on the mixing character of the neutralinos. In particular we study the dependence on the gaugino mass parameter M₁. (orig.)
