Differential Cross Section for Proton Induced Deuteron Breakup at 108 MeV

Abstract

The differential cross sections for the proton-deuteron breakup reaction have been measured for more than 200 angular configurations of outgoing protons in the range of polar angles from 13 to 27 degrees with a proton beam at 108 MeV. The paper presents the experimental results of the selected configurations, which are compared to state-of-the-art theoretical calculations. In some regions of the phase space, a strong influence of the Coulomb interaction is observed.

Experimental studies of the three nucleon system dynamics in the proton induced deuteron breakup at 108 MeV

“…The ∆E and E scintillator bars were arranged perpendicularly, what allowed to build twodimensional spectra for individual telescopes corresponding to their overlaps. On such particle identification spectra a good separation between deuterons and protons was observed [9,10].…”

“…The kinematic spectra (Fig. 2, right panel ) were then transformed to new variables, S vs. D, and after background subtraction the rate of breakup events in a function of variable S was obtained [9,10]. This rate was further corrected for the detection inefficiency and normalized to the integrated luminosity.…”

“…Determination of the correction for hadronic interaction effects has been reported in Refs. [10,12]. The correction associated with the configuration efficiency is related to losses of events in which two protons impinge on the same detector element.…”
