New Phase Space Calculations for β-Decay Half-Lives

Figure 1

(a) Electron density on the nuclear surface of state as a function of the atomic number of the parent nucleus. The values calculated with screening are displayed with filled circles and those without screening are plotted with empty symbols. The dashed lines are given to guide the eye. (b) Calculated PSF for EC as a function of the mass number of the parent nucleus. The filled circles display the calculation with screening, while the empty ones the calculation without screening.
