A general formal theory of resonance reactions and scattering is developed without the use of channel radii. The approach employed allows a simple physical interpretation of the two energies, one of which must be kept fixed while the other one is varied in order for a Breit-Wigner denominator to vanish. A new result, obtained without a weak channel coupling hypothesis, is that a sharp resonance niay be caused by forces which, if slightly different, would lead to a stable bound state even in the presence of strong coupling to open channels. The possibility of shapes other than the usual Breit-Wigner type is also discussed. A special formula is derived for resonances near a threshold caused by bound states just below that threshold in the same channels where the peak is seen. (auth)
