Abstract
We calculate $e^{+} e^{-}\to \tilde{t}_1\tilde{t}_1Z$ at a linear collider. For large splitting between the two stops, the cross section is sensitive to the value of $m_{\tilde{t}_2}$ when this particle is too heavy to be directly produced. The results are compared to $e^{+} e^{-}\to\tilde{t}_1\tilde{t}_1h$
