The populating of the excited levels of 83SE is poorly know and the gamma spectrum
will be anyway not correct (Not enough ENSDF data). Therefore this solution. Modification to solve a bug reported by 
.

Version 4.1 (February 2014)  Dennis Wright
------------------------------------------
- contains Laurent Desorgher's corrections for X,Y,Z,W and A levels.
  For consistency it should be used only with PhotonEvaporation3.1 or later
- D.H. Wright: added observationally stable (very long lifetime) ground states
               to 20 nuclides.  4 are thought to decay by alpha emission, 6 by
               double beta+ decay and 10 by double beta- decay.
               G4RadioactiveDecay.cc now recognizes double beta- and double
               beta+ decays, but currently does nothing when they occur.

Version 4.0 (September 2013)
----------------------------
- update to ENSDF 2012 by Laurent Desorgher

Version 3.7 (7 June 2013)

  were entered twice.  Duplicate entries were removed from these files:
  z37.a98, z37.a99, z38.a98, z38.a99, z39.a98, z39.a99,  z40.a98,  z40.a99,

  Missing decay information for excited states added to: 
  z47.a100, z60.a133

  Correct half-life and add missing decay information to:
  z20.a48

  Correct BetaMinus level 73.92 to 78.92 for
  z90.a234

  Recompute from latest ENSDF:
  z41.a100

  Remove BetaPlus and add Alpha decays:
  z100.a250

Version 3.6:
-----------
- Added new files containing the forbidden Beta decay information for all
  nucleus known to have such decays in the ENSDF database.
