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

Differential cross-sections for the elastic and inelastic scattering of [Formula: see text]-particles had been measured at the energy of 48.8[Formula: see text]MeV with excitation of low-lying states of the [Formula: see text] nucleus. The data for transitions to the ground [Formula: see text] and excited [Formula: see text], [Formula: see text] states relating to the ground state band were analyzed in the framework of the optical model and the coupled-channel method based on the rotational model. It is shown that the analysis is sensitive not only to the magnitude, but also to the sign of the quadrupole and hexadecapole deformations. The extracted values of the parameters [Formula: see text] and [Formula: see text] are in good agreement with the results of other experiments on the scattering of protons, [Formula: see text] and [Formula: see text]-particles and correspond to the data known from the electron scattering and Coulomb excitation.
