Remarks on the Mixed Multipole Internal Conversion Electron Correlation Parameters

Abstract
The internal conversion electron correlation parameters are calculated for the general K-shell (mixed) multipole conversion. Phase conventions are critically examined, and the sign of the mixed electric-magnetic conversion proposed by Church, Weneser, and Schwarzschild is verified. Phase conventions in the literature for the Dirac-Coulomb continuum wave functions are shown to be ambiguous, and a suitable standard convention is proposed.
