A New Tool to Interpolate Conversion Coefficients and E0 Electronic Factors

The internal conversion and electron-positron pair creation processes provide a versatile tool for investigating various aspects of the nuclear structure. The most recent calculations of Internal Conversion Coefficients, based on relativistic self-consistent Dirac-Fock calculations are widely regarded as the most accurate numerical results available today. The International Nuclear Structure and Decay Data Network has adopted the new conversion coefficients to replace the Hager and Seltzer, Rössel et al., and Band and Trzhaskovskaya tables. In this paper we report on the development of a new conversion electron data base and associated programs, which includes the new internal conversion coefficients tables, published in At. Data and Nucl. Data Tables 81, (2002) 1. Additional calculations have been carried out to extend the energy range, as well as improve the interpolation accuracy to obtain conversion coefficients in the 1-keV to 6000-keV region. Additional data tables have been compiled from published data to obtain values of electron-positron pair conversion coefficients and (E0) electronic factors
