Question Missing Implementation of Deuteron Elastic Cross Sections

Hello,

I want to study deuteron and antideuteron interaction with material at low energies (below 10 GeV), and by printing out the elastic and inelastic cross-sections implemented in Geant4, I noticed that the deuteron elastic cross section is actually not implemented at all: hardcoded to 0 in line 1320 of G4HadronCrossSections.cc. This was very surprising, since for antideuterons it is implemented (in G4ComponentAntiNuclNuclearXS.cc). Searching in this forum I found an old thread (http://hypernews.slac.stanford.edu/HyperNews/geant4/get/hadronprocess/608.html) which already pointed out this missing implementation. The answer was that it should be fixed in the G4UHadronElasticProcess class since version 8.1, but this class, as well as G4WHadronElasticProcess which followed in later versions, do not exist anymore. So my questions are:

1) Is there a reason for the missing implementation of the deuteron elastic cross-sections? Especially, why is it implemented for antideuterons but not for deuterons?

2)Can you suggest me any model that I could implement myself in order to fix this problem?

Note that this problem is valid not only for deuterons, but also for tritons and alpha particles.

Thank you and Best Regards,
