The reaction 2H(p,pp)n in three kinematical configurations at Ep=16MeV

We measured the cross sections of the ²H(p,pp)n breakup reaction at E_p=16MeV in three kinematical configurations: the np final-state interaction (FSI), the coplanar star (CST), and an intermediate-star (IST) geometry. The cross sections are compared with theoretical predictions based on the CD Bonn potential alone and combined with the updated 2π-exchange Tucson-Melbourne three-nucleon force (TM99'), calculated without inclusion of the Coulomb interaction. The resulting excellent agreement between data and pure CD Bonn predictions in the FSI testifies to the smallness of three-nucleon force (3NF) effects as well as the insignificance of the Coulomb force for this particular configuration and energy. The CST also agrees well whereas the IST results show small deviations between measurements and theory seen before in the pd breakup space-star geometries which point to possible Coulomb effects. An additional comparison with effective field theory (EFT) predictions (without 3NF) up to order N³LO shows excellent agreement in the FSI case and a rather similar agreement as for CD Bonn in the CST and IST situations.
