An important property—the dynamic deformation of B * light aligned nuclei—is investigated for the nuclear reactions A ( x, y ) B * → γ + B 0 by measuring the y -γ correlations. Dynamic deformation is determined from the orientation tensors of multipolar moments. Normalization constants of the contributions from even-rank orientation tensors are determined from the condition of coincidence between dynamic and static deformations of the B * nucleus for θ y = 0°. Experimental dynamic deformations of 12 C(2 + ) nuclei caused by the inelastic scattering of α particles and deuterons are determined, along with the 10 Be(2 + ) nuclei formed in reaction 9 Be(d, p) 10 Be(2 + ). It is shown that the dynamic deformation of the aligned nuclei depends on how they are formed and their structure, and evolves substantially when the angle θ y is varied.
