    "abstract": "The K-electron capture half-life of $^{123}$Te has been recently measured to\nbe $t^K_{exp}=2.4\\times 10^{19}$ yr, and constitutes the longest half-life ever\nmeasured in a single $\\beta$-transition of any nuclear species. We have\ncalculated this second unique forbidden transition within the framework of the\nproton-neutron quasi-particle random phase approximation, making use of\nSkyrme-type effective interactions. A strong cancellation effect between\nparticle-hole and particle-particle correlations is found. The model, without\nany renormalization of the force, provides a lower limit for the K-electron\ncapture half-life of $\\sim 10^{17}$ yr, which unambiguously rules out the old\nexperimental values of $10^{13} - 10^{14}$ yr. A few percent increase of the\nparticle-particle matrix elements of the Skyrme interaction allows to reproduce\nthe experimental findings.",
