SaG4n comes with its own version of the G4ParticleHP module (used to model the (alpha,xn) reactions), which is practically identical to that of Geant4, but with some minor modifications.

This release has been tested with Geant4.11.0, and is not expected to work with previous releases.

Some input examples are distributed together with the code. They are located inside the `inputs/examples` directory. Outputs generated with SaG4n using these inputs can be found in `outputs/examples_reference/`. They have been generated using Geant4.11.2.1 and the JENDLTENDL01 data library.

We have found some differences in the results of the examples compared to those distributed in previous releases of SaG4n. Specifically, in the results of `yields/yield01.inp` and `yields/yield03.inp`, which corresponds to the neutron production in Li and B. The differences come from changes in the Geant4, and not in SaG4n. If the inputs are run using Geant4.11.00.0, instead of Geant4.11.2.1, then the same results are obtained as those distributed in previous SaG4n releases.

The `outputs/examples` directory does not content any output file. The idea is to place there the output files generated by SaG4n, and compare then with the reference output files.

### fuel

`inputs/examples/fuel/`: here we calculate the neutron emission in PuO2. The geometry is a shpere made of PuO2, with a certain Pu isotopic composition. The alpha particles come from the decay of the different Pu isotopoes. We use the database introduced in SaG4n.01.04 to obtain the alpha spectra. The results are "per Bq", i.e. normalized to the number of alpha particles. There are two different inputs, which should lead to the same result:
- fuel01.inp: the intensities of the alpha spectra are provided for each Pu isotope.
- fuel02.inp: the intensities of the alpha spectra are not provided directly, but the half-lifes and isotopic abundances.
- `fuel01.inp`: the intensities of the alpha spectra are provided for each Pu isotope.
- `fuel02.inp`: the intensities of the alpha spectra are not provided directly, but the half-lifes and isotopic abundances.
