Description Fada Guan 2013-01-05 17:56:21 CET 
This value has been changed to 78 eV in the Geant4 code, but the manual is not updated yet.

Material: G4_WATER H_2O density: 1.000 g/cm3 RadL: 36.083 cm
 Nucl.Int.Length: 75.517 cm Imean: 78.000 eV
    ---> Element: H (H) Z = 1.0 N = 1.0 A = 1.01 g/mole
    ---> Isotope: H1 Z = 1 N = 1 A = 1.01 g/mole abundance: 99.99 %
    ---> Isotope: H2 Z = 1 N = 2 A = 2.01 g/mole abundance: 0.01 %

Comment 1 Michael Kelsey 2013-01-05 21:07:14 CET 
Thank you for creating this bug report.  I'm not sure when the Appendix in the Developers' Guide was created, but there have been a number of additions to the "NIST" (now much more than that) materials since then.  The Appendix will be updated from the GEANT4 9.6 release, and the new information will be included along with the 10.0 release this year.
Comment 2 Michael Kelsey 2013-01-05 23:53:48 CET 
The documentation source has been updated with the 9.6 "NIST" (so-called) materials database output.  If you need the current materials parameters before the public documentation is up to date, you may use the macro command

  /material/nist/listMaterials all
