Analysis of beta-decay data acquired at the Physikalisch-Technische Bundesanstalt: evidence of a solar influence

TL;DR

This paper presents evidence of solar influence on beta-decay rates, revealing oscillations linked to solar rotation, contradicting previous claims of no variability in decay data.

Contribution

It demonstrates the presence of solar-related oscillations in decay data, challenging prior assertions of decay rate constancy and providing new insights into solar effects.

Findings

Detection of 11-year solar rotation oscillation in decay data

Confirmation of oscillation through independent radon decay measurements

Contradiction of previous studies claiming no decay variability

Abstract

According to an article entitled Disproof of solar influence on the decay rates of 90Sr/90Y by Kossert and N\"ahle of the Physikalisch-Technische Bundesanstalt (PTB) [1], the PTB measurements show no evidence of variability. We show that, on the contrary, those measurements reveal strong evidence of variability, including an oscillation at 11 year-1 that is suggestive of an influence of internal solar rotation. An analysis of radon beta-decay data acquired at the Geological Survey of Israel (GSI) Laboratory for the same time interval yields strong confirmation of this oscillation.
