A large set of high precision vector and tensor analyzing power data of 1 H(⃗ d, pp)n breakup reaction was obtained at energy of 130 MeV. Studies of the breakup process with the use of polarized beams provide basis for thorough tests of the nuclear force structure. Such observables are sensitive to spin-dependent part of the interaction, what makes them interesting for testing theoretical calculations based on various approaches modeling the interaction in few-nucleon systems. The data presented as a function of a new set of invariants, introduced to describe the process with three nucleons in the final state, were confronted with the set of the modern calculations.

For technical reasons the number of authors shown on this cover page is limited to 10 maximum. A large set of cross-section data for the 1 H(d, pp)n breakup reaction was measured at 130 MeV deuteron beam energy with the Germanium Wall setup covering the range of very forward polar angles. In the investigated part of the phase-space, the dynamics is dominated by the Coulomb force influence. The data are compared with results of theoretical calculations based on the realistic Argonne V18 potential supplemented with the long-range electromagnetic component. The predictions also include the Urbana IX three nucleon force model. The cross-section data reveal seizable Coulomb force effects.
