# Example NeutronSource History

See `CONTRIBUTING.rst` for details of **required** info/format for each entry,
which **must** added in reverse chronological order (newest at the top). It must **not**
be used as a substitute for writing good git commit messages!

## 2025-11-14 Michel Maire (NeutronSource-V11-03-04)
- PhysicsList.cc: use local RadioactiveDecayPhysics instead of G4RadioaciveDecayPhysics

## 2025-11-05 Michel Maire (NeutronSource-V11-03-03)
- PhysicsList.cc: use G4EmStandardPhysics_option3 instead of opt4
                  add G4EmExtraPhysics as an alternative to GammaNuclearPhysics
		  use G4HadronElasticPhysicsXS instead of HP

## 2025-10-29 Michel Maire (NeutronSource-V11-03-02)
- GammaNuclearPhysics.cc: use G4GammaNuclearXS dataset

## 2025-08-04 Vladimir Ivanchenko (NeutronSource-V11-03-01)
- PhysicsList - removed temporary access to neutron capture model based
    on model name; removed unnecesary commented lines, used EM Opt4
    configuration for HP physics

## 2025-05-20 Michel Maire (NeutronSource-V11-03-00)
- NeutronSource.cc - SetUseNRESP71Model(true)

## 2024-02-20 Michel Maire  (NeutronSource-V11-02-00)
- PhysicsList: add G4HadronElasticPhysicsXS
- RadioactiveDecayPhysics: add Triton
- GammaNuclearPhysics, GammaNuclearPhysicsLEND: apply coding rules

## 2023-11-10 Alberto Ribon (NeutronSource-V11-01-01)
- In all macro files, introduced the UI command
  '/process/had/rdm/thresholdForVeryLongDecayTime 1.0e+60 year'
  to allow all radioactive decays (including the very long ones).
  This is necessary since G4 11.2, being 1 year the default time
  threshold above which the decays are ignored.

## 2023-07-12 Michel Maire (NeutronSource-V11-01-00)
- revision of all headers

## 2022-04-01 Michel Maire (NeutronSource-V11-00-01)
- PhysicsList: add G4NuclideTable::SetThresholdOfHalfLife(1ns*log2)

## 2021-12-10 Ben Morgan (NeutronSource-V11-00-00)
- Change to new Markdown History format
