- Аннотация: The angular dependence of the differential cross sections for alpha-particle scattering on Si-28 nuclei and double-differential cross sections for the reaction Si-28(alpha, alpha gamma)Si-28 at E (alpha) = 30.3 MeV is measured for the case of alpha-particle emission angle between 20A degrees and 160A degrees and the excitation of low-lying states of the Si-28 nucleus (0(+), ground state; 2(+) state at 1.78 MeV; 4(+) state at 4.62 MeV; 0(+) state at 4.96 MeV; and 3(-) + 4(+), 6.88 MeV + 6.89 MeV). The spin-tensor components of the density matrix for the 2(+) state at 1.78 MeV and the 4(+) state at 4.62 MeV in the Si-28* nucleus are reconstructed in a modelindependent way. Seven rank-6 components are reconstructed for the 3(-) state at 6.88 MeV. Orientation features of Si-28* are determined. The experimental data in question are compared with the results of the calculations performed under the assumption of the collective-excitation mechanism and by the coupled-channel method.
