- Abstract
- Temporal variations of nuclei decay parameters are actively searched now; their detection may be a signal of new physical effects of cosmic origin. Correlations of intensity of Co, Mn and Fe weak decay parameters with solar activity, with solar flares, were observed. In our work, correlations of X-class solar flares with Co and Fe decay rate variations measured via decay γ-ray detection by semiconductor detectors. For Fe decay the significant deviations of decay counting rate from the expected rate observed at the level -0.2% correlated with solar flares. For Co decay four similar events were detected with deviations at a level of ~0.4%. All decay rate deviations start from 30 to 155 hours before solar flare moments at confidence level of 90%.
