αγ angular correlations in the inelastic scattering of α particles on 24Mg at E α = 30.3 MeV

Abstract

The results from measuring the angular dependence of differential α-scattering cross sections on 24Mg with final nucleus formation in the ground and three lower excited states are presented, along with the double differential 24Mg(α, αγ)24Mg(2+, 1.369 MeV) reaction cross sections at E α = 30.3 MeV. The spin-tensor components of the density matrix of the 24Mg nucleus in the 2+(1.369 MeV) state are reconstructed and its orientation characteristics are determined. The experimental results are compared to theoretical results under the assumption of collective excitation and mechanisms for compound nucleus formation.
