Description
In this talk I explain how we can evaluate the fractions of the pi N and other meson-baryon molecular/cloud components for the N and Delta resonances from the pi N scattering amplitude in terms of the compositeness. Then I construct a simple model to discuss the internal structure of the Roper resonance N(1440) with the meson-baryon compositeness.
