摘要：

Several cases are discussed when an amplitude of resonance production is a sharply varying function of the resonance mass, leading to considerable differences between true and visible resonance parameters. The case of 4 He production is considered in more details. As all non-trivial features are caused by the peculiarities of the triangle graphs (threshold and proper-moving complex singularities near physical region), the possible methods of their visualization in inclusive cross sections and polarization effects are also studied.
