(a) The range of nuclear forces is of the order of 1 F so that the relevant Yukawa potential [see Eq. (12.42)] has m = 1 F-. Use this value to plot the differential cross section for Yukawa and Coulomb potentials as a function of q for a particle of incident momentum p= 10 GeV. can you tell the two.apart? (b) Discuss the physical assumptions implicit in the Yakas theory and its relation to the mass of the m-meson.
