We discuss a potential of studying the production and the decay of the lightest top squark (t̃1) in the framework of the supersymmetric standard model at a future e+e- collider. In particular, we consider the process t̃1 → tχ1 0 (with χ10 being the lightest neutralino) followed by t → bW. It is shown that, by the study of the angular distribution of the bottom quark (as well as the production cross section of the top squark), properties of χ10 can be extracted. We also discuss that, if χ10 is gaugino-like, the neutralino mixing parameters (i.e., the so-called μ-parameter and tan β) may be constrained.
