Systematic Measurement of pd Breakup Cross Section Around Space Star

Systematic measurement of D(p,pp)n cross section has been made at an incident energy of 13MeV around the space star configuration. In spite of the anomaly found in nd breakup cross section, no anomaly has been found in pd breakup.

Star Configurations

The~Space Star Anomaly in proton-deuteron breakup cross-section occurs at energies of about 10~MeV. Data for higher energies are sparse. Therefore, a~systematic scan over star configurations in the~range of intermediate energies between 50 and 100 MeV/nucleon is carried out on the~basis of data collected with the~large acceptance BINA detector. The~preliminary cross section results for forward star configurations at 80 MeV/nucleon slightly surpass the~theoretical calculations, but the~systematic uncertainties are still under study. Also, a~new variable describing rotation of star configurations is proposed.

Star Configurations

We measured D (p, pp)n cross section at Ep = 9.5 MeV and 13 MeV at off-plane star configurations, including the space star where the star is perpendicular to the beam axis. The experimental results were compared with recent pd breakup calculations using screened Coulomb force, and disagreement was found to smoothly vary with an inclination angle of the off-plane star, α. Further systematic experiments are necessary to investigate the star anomaly.
