Abstract

The phenomena of scaling and Bloom-Gilman duality are examined in the context of simple nonrelativistic and relativistic quantum-mechanical models. These models are shown to scale and to show the qualitative features of Bloom-Gilman duality. This suggests that these phenomena do not necessarily require the properties of QCD.
