Correlation Characteristics of the $${}^{{20}}$$Ne(2$${}^{{+}}$$, 1.634 MeV) Nucleus Formed in the $${}^{{19}}$$F($$\alpha$$, $${t}$$)$${}^{{20}}$$Ne Reaction at $${E_{\alpha}=30.3}$$ MeV

The differential cross sections of the $${}^{19}$$ F( $$\alpha$$ , $$t$$ ) $${}^{20}$$ Ne(g. s., 2 $${}^{+}$$ , 4 $${}^{+}$$ ) reaction studied at the cyclotron of the Skobeltsyn Institute of Nuclear Physics, $$t\gamma$$ angular correlations in the reaction $${}^{19}$$ F( $$\alpha$$ , $$t$$ ) $${}^{20}$$ Ne(2 $${}^{+}$$ ) at the energy $$E=30.3$$ MeV, and the tensors of the orientation $$t_{k\kappa}(\theta_{t})$$ of the multipole moments and the alignments $$F_{k}$$ ( $$\theta_{t}$$ ) of the $${}^{20}$$ Ne(2 $${}^{+}$$ ) nucleus reconstructed on their basis are compared with the calculated values under the assumption of a direct mechanism of proton stripping taking into account the coupling of channels using the Coupled-Channels Born Approximation method. A set of calculation parameters necessary for such a reaction mechanism was established and their specific values were determined. The calculated differential cross sections of the reaction $${}^{19}$$ F( $$\alpha$$ , $$t$$ ) $${}^{20}$$ Ne for all states of the rotational band agree with the experimental ones at $$\theta_{t}<120^{\circ}$$ , where the direct mechanism makes the main contribution. In the same region of $$\theta_{t}$$ , $$t_{k\kappa}(\theta_{t})$$ the calculated $$F_{2}$$ ( $$\theta_{t}$$ ) and $$F_{4}$$ ( $$\theta_{t}$$ ) of the $${}^{20}$$ Ne(2 $${}^{+}$$ ) nucleus agree satisfactorily with the experimental data. It was found that their value at $$\theta_{t}<120^{\circ}$$ is small, so the isotropy of the spin distribution in $${}^{20}$$ Ne(2 $${}^{+}$$ ) is not violated. At large angles $$\theta_{t}$$ , both the experimental and calculated values of $$F_{4}$$ are approximately 0.5, which indicates a partial violation of this isotropy.
