Transition rates of some forbidden lines in X-ray spectra

Abstract
The transition rates of the forbidden lines KLI, KMI, KNI and LIMI, LINI, LIOI have been calculated for the elements Z=60 to 92, using Dirac's unscreened hydrogenic wavefunctions. A fair agreement is found between the authors' values and the results of some earlier workers for the KLI transition. These calculations have enabled the authors to find the characteristics of the oscillator strengths for these forbidden lines.
