Abstract:

Electron-capture rates in highly evolved stars are calculated mainly with the help of the gross theory of β-decay for about 130 nuclei near the β-stability line (9 ≤Z ≤30, 20 ≤A ≤60). Special individual transitions whose contributions are important at relatively low densities and low temperatures are also treated separately. The numerical results for those rates are approximated by much simpler empirical formulas for convenience of practical use.
