Release Date:  15   May  1998


          The library contains input parameters for theoretical calculations of nuclear reaction cross sections.  Incident and outgoing particles can be n, p, d, t, 3-He, 4-He, and gamma with energies up to about 100 MeV.

          Numerical data are arranged in seven segments/directories (RIPL Starter File):

No Directory     

               Contents

1 MASSES Atomic Masses and Deformations
2 LEVELS     Discrete Level Schemes
3 RESONANCES Average Neutron Resonance Parameters
4 OPTICAL       Optical Model Parameters
5 DENSITIES Level Densities (Total, Fission, Partial)
6 GAMMA Gamma-Ray Strength Functions
7 ANGULAR Continuum Angular Distributions

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

         Principal and most useful role in the project played official participants, followed by active additions from other contributors as listed below.  Tribute to many further scientists whose work so valuably contributed to the library is reflected, to the extent possible, in the file names and in due reference to their work.
