Data confidence 70 medium
How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Elastic-scattering processes in the $${}^{3}\textrm{He}+{}^{9}$$ Be reaction are studied on the basis of the 2 $$\alpha+n$$ three-body cluster model of the $${}^{9}$$ Be nucleus. The $${}^{9}$$ Be three-body wave function obtained by the variational method in the Gaussian basis is used to derive an analytic representation of nuclear-matter density distribution. The interaction potential calculated for the $${}^{3}\textrm{He}+{}^{9}$$ Be system by the double-folding method is employed to analyze experimental data on the differential cross section for the elastic-scattering process $${}^{9}$$ Be ( $${}^{3}$$ He, $${}^{3}$$ He) $${}^{9}$$ Be at collision energies between 30 and 60 MeV.
