N2 - A new internal conversion coefficient database, BrIcc has been developed which integrates a number of tabulations on internal conversion electron (ICC) and electron-positron pair conversion coefficients (IPC), as well as Ω (E 0) electronic factors. A critical review of general formulae and procedures to evaluate theoretical ICC and IPC values are presented, including the treatment of uncertainties in transition energy and mixing ratio in accordance with the Evaluated Nuclear Structure Data File. The default ICC table, based on the Dirac-Fock calculations using the so called "Frozen Orbital" approximation, takes into account the effect of atomic vacancies created in the conversion process. The table has been calculated for all atomic shells and to cover transition energies of 1-6000 keV and atomic numbers of Z = 5-110. The software tools presented here are well suited for basic nuclear structure research and for a range of applications.
