Abstract
We present a rigorous method for accurate ab initio calculations of the electron electric-dipole-moment -odd interaction constant . The approach uses configuration interaction wave functions and Dirac four-component spinors as one-particle basis functions, and the interaction constant is obtained as an expectation value over these correlated wave functions. We apply the method to the HfF molecular ion and determine spectroscopic constants for four low-lying electronic states. For one of these states () we determine the effective electric field (), which amounts to 23.3 GV/cm, correlating 34 valence and outer atomic core electrons and using wave-function expansions with nearly coefficients.
