Abstract
We study the associated production of selectrons and neutralinos with subsequent leptonic decay of the selectron in eγscattering within the framework of MSSM and NMSSM. Due to the weak couplings of singlino dominated neutralinos, associated neutralino production e^+ + e^- -> neutralino_1 + neutralino_2 at a linear collider can be strongly suppressed in some regions of the parameter space. Then the process e + gamma -> selectron_{L/R} + neutralino_{1/2} -> e + neutralino_{1/2} + neutralino_1 can give additional informations on the underlying theory and the character of neutralino_1 and neutralino_2.
