Bounds on Scattering Phase Shifts for Compound Systems

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. It might be noted that the same remarks are applicable for compound system scattering with regard to the error introduced by truncation as were applicable for one body scattering. As examples, consider the scat tering of electrons or positrons by Hydrogen. An estimate based on the method of the present paper is that for R of the order of 15 Bohr radii.
