     ---------------------------------------------------------

23 November2016 Vladimir Ivanchenko  PhotonEvaporation4.3
--------------------------------------------------------------  
 New data files moved to subdirectory correlated_gamma
 Files from PhotonEvaporation3.2 are restored for Geant4 release 
 10.3
     
 8 November2016 Laurent Desorgher  PhotonEvaporation4.2
--------------------------------------------------------------  
 Correct 12 lines with mispelled data in the whole database
 
 Correct the order of levels in  files z58.a133, z64.a148, z64.a149, z64.a150, z65.a151, z72.a174,
       z81.a192,z81.a194,z82.a193 
 Correct few gamma energies
 
 Update z90.a231 for U235 decay with data form the DDEP http://www.nucleide.org/DDEP.htm
 
 19 October 2016 and 2 November 2016 Laurent Desorgher  PhotonEvaporation4.1
--------------------------------------------------------------
-Reformatting of z* files. Correction of few data in these files.
 Checking of the format has been added in the python test suite.
-Remove PhotoEvaporation3.2 z*.a* files
-Add explode files z*.a*  from z* files.
-Correction of few gamma intensities in z6.a12, z16.a33,z17.a42,z34.a76,z38.a95,z38.a97,
           z41.a88,z56.a129,z74.a187
-Remove deexcitation of levels on it self.
          
 


 16 September 2016 Laurent Desorgher         PhotonEvaporation4.0
-----------------------------------------------------------   
-Merging in the same database of the PhotoEvaporation3.2 z*.a*.txt files and the 
 new photoevaporation data files.
 The new data files are updated with  floating levels, multipolarity and mixing ratio data.
 The new files are in Z*.txt files.
 The README for the new data is the file README-LevelGammaData_Extended.
 

 6 November 2015 Dennis Wright         PhotonEvaporation3.2
-----------------------------------------------------------
- package Laurent Desorgher's new version of photon evaporation database
  which is meant to be consistent with the 4.3 version of the radioactive 
  decay database.  It is also formatted to remove scientific notation
  where possible and to remove trailing zeros. 
 
19 February 2014 Dennis Wright         PhotonEvaporation3.1
-----------------------------------------------------------
- contains Laurent Desorgher's corrections of of +X, +Y, ... levels for
    compliance with latest isomer list
- problem report 1565: propagate bug fix in NUDAT2 to PhotonEvaporation:
    212Bi (z83.a212, line 8), change strength of gamma transition
    (415.272 keV to ground state) from 4.4 to 0.4. 

3 September 2013  Laurent Desorgher    PhotonEvaporation3.0
-----------------------------------------------------------
- update to August 2012 version of ENSDF

7 November 2013  Dennis Wright
-----------------------------------------------------------
- update README with Michel Maire's corrections
