BrIcc Data Tables BrIcc v2.2a

Conversion Coefficient Calculator based on commonly used 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.

^g For K-, L-, and M-shells: Z=30–103; for N+ shell Z=37–100 ^h For K-shell: ε_ic+1 – 1500(1650) keV; for L-shell: ε_ic+1 – 1000(1550) keV; for M-shell: ε_ic+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.
