Investigation of three nucleon force effects in deuteron–proton breakup reaction

Experiments devoted to study subtle ingredients of nuclear dynamics were carried out at KVI in Groningen with the use of the $^{1}H\left ( d,pp \right )n$ breakup reaction at the deuteron beam energy of 80 MeV/nucleon. The aim of the work is to determine the breakup cross sections and confront them with the set of modern calculations which model forces acting between nucleons. Elastic scattering process was also measured for the purpose of the cross section normalization. This paper presents preliminary results of the data analysis including geometry cross check, energy calibration, particles identification and sample distributions of the unnormalized breakup cross sections.
