Polarisation der Protonen aus der Reaktion¹⁰B(d, p ₀)¹¹B bei Deuteronenenergien von 1,15, 1,40 und 1,85 MeV

Abstract

Angular distributions of the polarization of protons from the reaction¹⁰ B(d, p ₀)¹¹ B have been measured between 20 and 148° at deuteron energies of 1.15, 1.40 and 1.85 MeV. Measurements were made by double-scattering techniques using elastic scattering from carbon as the analyser. The results show a strong energy dependence and are in significant accordance with¹⁰ B(d, n ₀)¹¹C data. Calculations have been performed for the mirror reactions¹⁰B(d, p ₀)¹¹B and¹⁰B(d, n ₀)¹¹C in the framework of the Simon and Welton theory assuming two broad compound-states in¹²C, a 2⁺ state at 26.02 MeV and a 3⁻ state at 26.89 MeV excitation energy.
