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 processes of K+- and K−-meson production in reactions Ne+NaF , Ne+Pb and Si+Si at E kin =2.1 GeV/N are considered within the framework of the nuclear pionization model. Model calculations are in agreement with experimental data. It is shown that K+-mesons having small absorption cross-section are produced at the relatively early stage of the cluster expansion whereas K−-mesons having large absorption cross-section are produced simultaneously with pions at the relatively late stage of the process.
