Analyzing the orientation characteristics of 12С(2+; 4.44 MeV) nuclei in the inelastic scattering of α particles on carbon at Eα = 16–25 MeV

Abstract

All even components of the spin-tensors of a density matrix reconstructed by means of angular correlation for ¹²С nuclei in the 2⁺ state (4.44 MeV), produced during the inelastic scattering of α particles with energies of 16 to 25 MeV in scattering angle range θ_α(lab) = 20°–90°, are presented. The energy dependences of its orientation characteristics (i.e., the population of magnetic substates and the orientation tensors of multipole moments) are determined. Experimental results are compared to calculations using the coupledchannel method and the compound nucleus model.
