Several options for decay data are available:
(They are used for isomeric ratios and cumulative yields.)

JEFF3.1.1:   
Include NucProb.bas in GEF.bas

ENSDF and other extensions:
Include NucProbx.bas in GEF.bas

NucPropf: Special version for fissioning nuclei:
(For shape isomers.)
Isomers in ground-state minimum (no shape isomers)

NucPropmf: Special version for fissioning nuclei:
(For neutron-induced fission on isomer targets.)
Shape isomers added (no other isomers of fissioning nuclei)
