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

The elastic and inelastic scatterings of α-particles were investigated at an energy of 29 MeV with excitation of lowlying states of the 11B nucleus. As a result of research we obtained new experimental data for the α + 11B inelastic scattering one leading to the 2.12 MeV (1/2−), 4.44 MeV (5/2−) and 6.74 MeV (7/2−) excited states of 11B nucleus. In the framework of Modified diffraction model, the root mean square radii of these excited states are calculated. The theoretical calculations for the concerned excited states were performed using the coupled channel (CC) method.
