Direct determination of the atomic mass difference of ¹⁸⁷Re and ¹⁸⁷Os for neutrino physics and cosmochronology

ATOMIC MASSES ¹⁸⁷Re, ¹⁸⁷Os; measured cyclotron-frequency ratio of ¹⁸⁷Re and ¹⁸⁷Os ions, mass difference using Penning-trap mass spectrometer SUIPTRAP at GSI facility; deduced Q value for ¹⁸⁷Re decay. Comparison with previous experimental results. Possibility of electron capture by ¹⁸⁷Os ions in hot stellar conditions.

RADIOACTIVITY ¹⁸⁷Re(β^-); measured precise Q value from mass difference of ¹⁸⁷Re and ¹⁸⁷Os ions using SHIPTRAP at GSI. Comparison with other results. Relevance to cosmochronology.
