Abstract
The results from measuring the 27Al(p, α)24Mg reaction’s differential cross sections at E p = 7.4MeV with the formation of the final nucleus in the ground and first excited (2+, 1.369 MeV) states are presented. The differential cross sections are obtained in the 25°–160° (lab) range of α-particle emission angles. Double-differential cross sections for the 27Al(p, α1γ)24Mg reaction are measured at the same proton energy for several α-particle angles in the forward hemisphere. All even components of the density matrix spin tensors of the 24Mg nucleus in the 2+ (1.369 MeV) state are reconstructed and its orientation characteristics are determined. The experimental results are compared with calculations for the triton pickup mechanism using coupled channels, and in the the statistical limit of the compound nucleus model.
