EXFORTABLES-2.2 - An experimental nuclear reaction database based on EXFOR

a PhD in the Natural Sciences on Multi-step direct reactions at the Univ. of Groningen, and a Professorship at the Univ. of Uppsala on theoretical nuclear reactions.Arjan is currently Head of the Nuclear Data Section at the IAEA in Vienna.Before that, he has worked at ECN/NRG Petten, the Netherlands, on nuclear reaction data for science and technology, and as guest scientist at CEA/Bruyères-le-Châtel and Los Alamos National Laboratory on the development and computational implementation of nuclear reaction models.He has led several students to PhD degrees, has coordinated and chaired various international nuclear data projects such as the OECD/NEA JEFF and WPEC projects, and has advised governments and international organisations on nuclear research and development.Among his scientific accomplishments are innovations in nuclear reaction physics, especially for the optical model and pre-equilibrium reactions, and initiating the '3 T's': the TALYS nuclear model code, Total Monte Carlo uncertainty propagation and the TENDL nuclear data library.He has been awarded the Oppenheimer Coin from Los Alamos National Laboratory, and the title of Doctor Honoris Causa by Uppsala University.As of 2025, his h-index is 62 with more than 26 000 citations.Although Arjan is currently in a managerial role, he aims to keep his scientific creativity alive by maintaining and extending TALYS plus all software that emerges from that.Pleas from his friends to also spend time on other things are sometimes honoured. PrefaceEXFORTABLES is a directory-structured database with experimental nuclear reaction data.It is entirely based on the international experimental nuclear reaction database EXFOR but, unlike EXFOR, contains the data in an easy accessible projectile/element/mass/reaction directory structure.A code exfortables.f90has been written which reads in the entire EXFOR database and produces EXFORTABLES.During this database translation, statistical tests are performed on almost the entire EXFOR database and the results of these tests are written to various diagnostic files, which can be taken into account by the Nuclear Reaction Data Centres network to correct EXFOR.The idea to make EXFORTABLES was born in 2006, when I argued that in these times of strongly increasing computer power, the mining of experimental data from EXFOR, and assessing their correctness, is rapidly becoming one of the main delaying factors in data evaluation.Fortunately, several others had the same opinion and soon the NEA WPEC Subgroup 30 on the "Quality improvement of the EXFOR database" took off to address this issue.The current database is one of the results of that.At certain moments in time, a well-defined version of EXFORTABLES is frozen.You are now reading the tutorial of version 2.2.For some reason, it took me 10 years to release this software and tutorial, so meanwhile other initiatives and visions on the availability of EXFOR are starting to emerge.EXFORTABLES translates the entire EXFOR database at once while it may be more flexible to have user-defined EXFOR retrievals via a dedicated API.Until that has been accomplished, there is EXFORTABLES, and later the results from the two approaches can always be compared.
