Description
Summary:At the proton energy of [E.sub.p] = 7.4 MeV, the double-differential cross sections for the reaction [sup.27]Al(p, [[alpha].sub.1][gamma])[sup.24]Mg were measured for 11 values of the alpha-particle emission angle in the range of [[theta].sub.[alpha]] = 30[degrees]-160[degrees] (lab). All even components of the density-matrix spin-tensors were reconstructed for the oriented [sup.24]Mg nucleus in the [2.sup.+] state at 1.369 MeV, and the polarization features of this nucleus, including the populations of magnetic sublevels of the nucleus for all spin projections, multipole-moment orientation tensors, and the quadrupole and hexadecapole tensor polarizations, were determined. Relevant experimental results were compared with their counterparts calculated for the triton-pickup mechanism within the coupled-channel method and in the statistical limit of the compound-nucleus model.
