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

Interference correlations of neutral-kaon pairs produced in the interactions of 20-to 70-GeV neutrons with a carbon target are studied by using the EXCHARM spectrometer. Constructive correlations at low relative 4-momenta are observed for K S 0 K S 0 pairs. The kaon-generation radius is determined.
