ftValues andLKRatios for Orbital Electron Capture

Abstract

The calculation of// values for allowed and first forbidden orbital electron capture transitions is discussed. It is shown that ft values for A/=l, yes, orbital electron capture transitions, calculated using allowed/ functions, can be compared directly with ft values for similar transitions involving beta particle emission. The L/K electron capture ratios for Al~ 1, yes, transitions are shown generally to be the same as for allowed transitions of similar energy for a given element. Comparison with experimentally measured L/K capture ratios is made.
