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 ⁶⁰Co, ⁵⁴Mn and ⁵⁵Fe weak decay parameters with solar activity, with solar flares, were observed. In our work, correlations of X-class solar flares with ⁶⁰Co and ⁵⁵Fe decay rate variations measured via decay γ-ray detection by semiconductor detectors. For ⁵⁵Fe decay the significant deviations of decay counting rate from the expected rate observed at the level -0.2% correlated with solar flares. For ⁶⁰Co 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%.
