Hello,

I am using RadioactiveDecay for the simulation of different Nuclids.

A nuclide like 108Ag wich has two entries in the data-base:

# 108AG (2.37 m)
#  Excitation   Halflife Mode       Daughter Ex  Intensity           Q
P     0.00000  1.422E+02
                         BetaPlus       0.00000  2.828E-03
                         KshellEC       0.00000  2.219E-02
 ...etc. ...

# 108AG (418 y)
#  Excitation   Halflife Mode       Daughter Ex  Intensity           Q
P   109.44000  1.319E+10
                         IT           109.44000  8.700E-02
                         BetaPlus       0.00000  0.000E+00
                         KshellEC       0.00000  7.720E-01
                         LshellEC       0.00000  1.130E-01
                         MshellEC       0.00000  2.798E-02
                         KshellEC    1771.16200  7.720E+01   256.27800
                         LshellEC    1771.16200  1.130E+01   256.27800
                         MshellEC    1771.16200  2.798E+00   256.27800

how can I distinguish between these two?

In other libraries the excited 108Ag is called Ag108m.

Is the way to specify the excitation energy like \gun\ion 47 108 0 109.44 and that means, GEANT4 only uses the decay for Ag108m?

Thanks Karen
