NeutronHP and G4NDL update

The latest update to NeutronHP and G4NDL (version 3.15) brings significant improvements, including the full replacement of current data—no more unknown origin data. Backward compatibility is maintained for existing data formats. All ENDF VII.0 isotopes (354 total) are included, featuring natural abundance data for isotopes from 1H1 to 100Fm255. Additional modifications enhance handling of MF6MT102 and introduce protections for high order Legendre coefficients. This update aims to streamline usage, with new inelastic/gamma data, while excluding unsupported excited isomer data.

  1. NeutronHP and G4NDL update KOI, Tatsumi

  2. Update G4NDL3.15 • Current data will be fully replaced (No more unknown origin data) • Still they can be used (keep backward compatibility for a while) • Converted all the data of ENDF VII.0 with several exceptions • From 1H1 to 100Fm255 (354 isotopes with 3 natural abundance data) • NJOY Error • 90Th232 • Negative XS • 17Cl35 • Comp reactions without MT 4(n), 103(p), 104(d), 105(t), 106(He3), 107(z) • 4Be7, 33As74, 33As75, 39Y90, 91Pa231 and 91Pa233 • Exclude excited isomer data (cannot use in Geant4) • 27Co058m1, 47Ag110m1, 48Cd115m1, 52Te127m1, 52Te129m1, 61Pm148m1, 67Ho166m1, 95Am242m1 and 95Am244m1 • Add line-gamma data from Np to Cf into Inelastic/Gammas • Public G4NDL3.15 will include the data up to U (with fission data)

  3. Update NeutronHP • Enable to handle MF6MT102 • Unsupported format of description of final states from capture reaction • Protection for the high order Legendre coefficients • ENDF 6 allows up to 64. • Currently NeutronHP only handles 30. • Read QI values and LF (break-up flag) • Not yet used • Keep backward compatibility • Many other modifications for handling ENDF-VII.0 • Do we remove the protection for Z>92?

  4. Special thanks for the organizer and attendants of mini-workshop at CIMIAT in this March
