Dynamic deformation of light nuclei in excited states

Abstract

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 deter mined 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.
