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

Abstract In this manuscript, we examine the radiative beta decay of free neutrons measured by the RDK II collaboration. The infrared portion of the emitted photon spectrum is shown to corroborate a thermal distribution consistent with the dynamical Casimir effect (DCE). We find the system is thermalized at the local Fulling-Davies-Unruh temperature predicted by the DCE. Substantiated by an excellent chi-squared statistic, we present the evidence for the observation of thermal radiation emitted during the beta decay process in accordance with an accelerated moving mirror.
