The calculation of cross-sections for stable target nuclei and unstable nuclei with half-lifes more than 10 minutes was performed using the TALYS code. Cross-sections for target nuclei with the decay half-life 1 sec < T1/2 < 10 min were obtained using the ALICE/ASH code.
Calculations for isomeric targets with T1/2 > 1 hour were carried out by TALYS. Approximate data are included in the present version of PADF for other short-lived isomeric targets.
Isomeric residuals are presented in PADF for nuclei with T1/2 > 1 sec.
Experimental cross-sections available in EXFOR for proton induced reactions, (p,x) including (p,gamma), were used for the correction of calculated excitation functions and the cross-section evaluation. This involved cross-sections for independent (non-cumulative) residual yields from 1434 EXFOR data sets. PADF includes also calculated neutron-, proton-, deuteron-, triton-, 3He-, a-particle- and g-production cross-sections. PADF is available in pointwise and groupwise data format.
The pointwise data are presented in standard ENDF-6 format.
The groupwise format of PADF is the same as the one used for IEAF data. The 256 group data files were generated using the NJOY code. The 175 group structure of VITAMIN-J was adopted at energies below 20 MeV. The energy bin of 1 MeV was used for the energy range from 20 to 50 MeV and 2 MeV - bin for energies from 50 to 150 MeV.
