ftValues andLKRatios for Orbital Electron Capture

The calculation of $\mathrm{ft}$ values for allowed and first forbidden orbital electron capture transitions is discussed. It is shown that $\mathrm{ft}$ values for $\Delta I=1\mathrm{}$, yes, orbital electron capture transitions, calculated using allowed $f$ functions, can be compared directly with $\mathrm{ft}$ values for similar transitions involving beta particle emission. The $\frac{L}{K}$ electron capture ratios for $\Delta I=1\mathrm{}$, yes, transitions are shown generally to be the same as for allowed transitions of similar energy for a given element. Comparison with experimentally measured $\frac{L}{K}$ capture ratios is made.
