摘要
Deuteron breakup differential cross sections and analyzing powers for scattering at E (d) = 16 and 130 MeV are examined using the energy-independent quark-model nucleon-nucleon interaction fss2. The Coulomb effect is incorporated by the sharp cut-off Coulomb force, acting between quarks, without the phase-shift renormalization for the breakup amplitudes. Our results are very similar to those by the meson-exchange potentials, including disagreement for some specific kinematical configurations. The accurate and systematic KVI data at E (d) = 130 MeV are reasonably reproduced by taking the Coulomb cut-off radius rho a parts per thousand yen 16 fm.
