Background

The practical use of nuclear reaction model codes requires a considerable numerical input that describes properties of the nuclei and interactions involved.  The Reference Input Parameter Library represents a fairly comprehensive set of such parameters, collected and selected from sources all over the world.

RIPL contains input parameters for theoretical calculations of nuclear reaction cross sections.  The library is targeted at users of nuclear reaction codes interested in low energy nuclear applications. Incident and outgoing particles can be n, p, d, t, 3-He, 4-He, and gamma with energies up to about 100 MeV.

RIPL is being developed under the international project coordinated by the IAEA.  The phase I of the project, conducted in 1994-1997, resulted in the RIPL Starter File (numerical data) and the RIPL Handbook (description).


RIPL Starter File

The Starter File contains numerical data organized into 7 segments/directories:

Each segment/directory is split into 2 subdirectories:
        · RECOMMENDED (for recommended input parameters), and
        · OTHER_FILES (for alternative input parameters and other useful data).


RIPL Handbook

The Handbook (about 150 pages) contains description of the library, including the physics involved. It consists of Introduction, 7 Chapters describing actual parameters and Appendix. Chapters follow the structure explained above, Appendix includes the list of files in the Starter File and reproduces (hardcopy version only) 2 important papers devoted to optical model. The Handbook, available electronically in LaTeX and PostScript formats, will be published also as a hardcopy (IAEA TECDOC series, expected to appear by the end of 1998).


On-line access

Access, restricted to read only, can be achieved via the Web interface or using FTP. The address of the Web site is

while for FTP one should use

CD-ROM

Complete library (RIPL Starter File and RIPL Handbook) on a CD-ROM is available from the IAEA Nuclear Data Section cost-free upon request .


File Naming Convention

As a rule,  RIPL file names are created by coupling together 3 words, yielding full names with the structure

                        originator_explanation.type

As  originator we use the name of a laboratory if the file came from a participant of the RIPL Coordinated Research Project (CRP).  In cases where files came from individuals outside the CRP, names of these individuals are used.  The ripl is used for files generated by the whole RIPL team. Thus, the main originators are beijing, bologna, bombay, budapest, jaeri, livermore, losalamos, obninsk and ripl.   In addition, the individual originators are audi, avrigeanu, capote, iljinov, kalbach, kopecky, maslov, mengoni and moller and varlamov.

Explanation indicates the contents of the file. Since the name of the basic directory serves this purpose, explanation is generally omitted. However, it is always given when more than one file in one subdirectory has the same originator.

Type reflects the type of data in the file:
