Data tables

  • BrIccFO (default & recommended) - 'Frozen Orbitals' approximation to take into account the effect of the hole.
  • BrIccNH - 'No Hole' approximation which ignores the effect of the hole.
  • HsIcc - Hager-Seltzer and Dragoun et al. tables.
  • RpIcc - Rösel et al. tables.

a εic is the binding energy for the ic-shell
b Used for Z < 50
c Electronic factors are only calculated for even Z values at present
d Not used
e Used for Z < 40
f For Z=40–58: 51.1 keV; for Z=60–82: 102.2 keV; for Z=84–96: 153.3 keV and for Z=98–102: 204.4 keV

HsIcc data set

Data Table Reference Z Shells L Transition energy [keV] a
Internal Conversion Coefficient (ICC) i
HsIcc Based on the Hager and Seltzer 1968Ha53 and Dragoun et al. 1971Dr11 tables 30–103 K, L, M
and N+ shellsg
1–4 εic+1–1500h
g For K-, L-, and M-shells: Z=30–103; for N+ shell Z=37–100
h For K-shell: εic+1 – 1500(1650) keV; for L-shell: εic+1 – 1000(1550) keV; for M-shell: εic+1 – 150(510) keV;
  for N+ shell: 50 – 500 keV
i K-, L- and M-shell ICC values for L=3 and 4 multipolarities have not been scaled as recommended by 1990Ne01.
  ICC values should be multiplied by 0.975 (10) for L=3 and 0.975 (5) for L=4 to agree with values from HsIcc.

RpIcc data set

1.1 31-Aug-2004 In house (ANU) testing of the first version of the program completed.
1.2 24-Sep-2004 Bechmark testing (NNDC) of the first version of BrIcc completed.
1.3 19-Nov-2004 ANU web interface created.
1.3 20-Dec-2004 BrIcc relesed for ENSDF evaluators.
6-Jun-2005 NSDD coordination meeting ( McMaster) adopted the 'Frozen Orbitals' approximation.
2.0 1-Sep-2005 Tabulations using the 'Frozen Orbitals' approximation completed. BrIcc program logic, exception and error handling improved.
2.1 1-Oct-2005 BrIccS ('slave') version developed and the new ANU web interface created.
2.0a 19-Dec-2005 Corrected a bug in the BrIcc MERGE operation.
2.0b 12-Jan-2006 Corrected a bug in the BrIcc MERGE operation.
2.1 28-Feb-2007 User selectable data tables, including BrIccFO, BrIccNH, HsIcc and RpIcc were added to the ANU web interface.
27-Apr-2007 The Decay Data Evaluation Project (DDEP) has adopted BrIcc and the 'Fozen Orbitals' approximation.
2.2 4-Jan-2008 The BrIccFO and the BrIccNH data tables have been recalculated for several chemical elements (see Table B1 of the NIM paper) and the range of the tables have been extended for Z=5–110.
