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

We applied the thick target inverse kinematics method for a study of resonances decaying through neutron emission.In this approach, the time of flight of the resonant neutrons is defined by the movement of the heavy ions of low-energy beams through an extended target.As a test, we used a well-studied, because of its role in the s process in stars, 13 C(α, n) reaction.The measurements demonstrated the high efficiency of the approach.The energy resolution for the 13 C(α, n) excitation function was ≈60 keV, the largest contributions coming from the time structure of the beam and the thickness of the neutron detector.The measurements revealed a surprising disagreement with the R-matrix calculations based on the parameters of the recent analysis.
