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

Within Glauber diffraction theory, the vector analyzing power iT 11 is calculated at three energies of positively charged pions, 134, 164, and 194 MeV, incident to 7 Li nuclei. These energy values lie in the region of the Δ 33 resonance in π ± N interaction, the resonance maximum being at 180 MeV. The calculation of iT 11 was performed with several model 7 Li wave functions, including the αt -cluster and shell-model ones. The properties of π +7 Li scattering are found to be sensitive to the structural features of the target nucleus. A comparison of the results of the calculations with experimental data shows that the wave functions in question and the potentials used to calculate them are quite appropriate.
