Proton–proton phase shifts calculations in momentum space by a rigorous Coulomb treatment

Abstract

We present a two-body calculation method for a rigorous treatment of Coulomb interaction in momentum (p-)space. The method is based on a modified Coulomb potential which is equivalent to the genuine Coulomb potential in configuration (r-)space. We also use the two-potential theory with the auxiliary potential. The calculated proton–proton phase shifts are in very good agreement with the experimental data for the states 0 ⩽ l ⩽ 2. The phase shifts for the 3 ⩽ l ⩽ 5 states are also calculated. Practical applications of our method in a few hadron problems are discussed.
