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 of proton scattering on 9 B and 9 Be nuclei are calculated using the Glauber theory at energies of 135, 180, 220, and 1000 MeV. The wave function (WF) in a three-particle 2α + N model with paired αα and α N interactions with states forbidden by the Pauli principle is used in deriving the matrix elements. The geometric structure of 9 B WFs calculated using different potentials of the αα interaction is investigated. The contribution to the collision cross sections of different orders in the Glauber operator Ω is calculated. It is shown that single and double collisions must be taken into account, while triple collisions make almost no contribution to a cross section.
