Credit/citations for data files distributed with Geant4

We acknowledge the use of external data libraries in compiling the Geant4 data libraries.
Information on these sources is currently provided also in our publications, including NIM A 506 (2003), 250.

Radioactive Decay

The radioactive decay data comes from the Evaluated Nuclear Structure Data File (ENSDF) which is maintained by the National Nuclear Data Center, Brookhaven National Laboratory.

G4NDL (with and without thermal neutrons)

G4NDL data comes largely from the ENDF/B-VI library which is developed and maintained by the Cross Section Evaluation Working Group (CSEWG). The original data files may be accessed at the National Nuclear Data Center web site.

G4NEUTRONXS (evaluated neutron cross sections)

Evaluated data are produced using the G4NDL data set via averaging procedure for neutron energies E<10 MeV. For energies E>20 MeV the cross-sections are computed by Geant4 cross-section classes G4BGGNucleonInelasticXS and G4BGGNucleonElasticXS. For the interval E=10-20 MeV a linear interpolation is used.

G4ABLA (nuclear shell effects)

The data are based on ABLA V3 data files:

flalpha.dat - alpha ground state deformation
frldm.dat - ground state shell corr. frldm for a spherical g.s.
vgsld.dat - difference between deformed g.s. and ldm value
pace2.dat - default mass for A, Z nucleus

The data are meant to be used for the INCL/ABLA hadronic models (located in Geant4 in processes/hadronic/models/incl).

Photon Evaporation

Photon evaporation data comes from the Evaluated Nuclear Structure Data File (ENSDF) which is maintained by the National Nuclear Data Center, Brookhaven National Laboratory.

G4EMLOW (Low energy electromagnetic)

Livermore models data (except for the photoelectric_angular module) are derived from the Livermore data libraries:

EPDL97 - Evaluated Photon Data Library
EEDL - Evaluated Electron Data Library
EADL - Evaluated Atom Data Library

Data related to the Geant4-DNA extension have been collected from published material and/or by courtesy of their author. They are described in the following publications:

C. Champion et al., A free-parameter theoretical model for describing the electron elastic scattering in water in the Geant4 toolkit, Rad. Phys. Chem. (2009)
S. Chauvie et al., Geant4 physics processes for microdosimetry simulation: design foundation and implementation of the first set of models, IEEE Trans. Nucl. Sci. 54 (6-2) (2007) 2619-2628

The data have been reformatted for usage in Geant4 and some files contain values resulting from fitting of the original data.
Data related to PIXE simulation are collected from the available literature.

Real Surface data (measured optical surface reflectance LUT)

The data for measured optical surface reflectance look-up tables are described in:

M. Janecek and W.W. Moses, Simulating Scintillator Light Collection Using Measured Optical Reflectance, IEEE Trans. Nucl. Sci. 57 (3) (2010) 964-970
