Release Date: April 20, 2003

RIPL-2 library contains input parameters for theoretical calculations of nuclear reactions involving light particles such as n, p, d, t, 3-He, 4-He, and gammas at incident energies up to about 100 MeV. The library contains nuclear masses, deformations, matter densities, discrete levels and decay schemes, spacings of neutron resonances, optical model potentials, level density parameters, Giant Resonance parameters, gamma-ray strength-functions, and fission barriers. It also includes extensive database of level densities, gamma-ray strength-functions and fission barriers calculated with microscopic approaches. Several computer codes are provided in order to facilitate use of the library.

RIPL-2 has been developed under an international project coordinated by the IAEA Nuclear Data Section as a continuation of the RIPL-1 project concluded in1997. The original scope of RIPL-2 was to test and validate RIPL-1 database. In the course of work most of the recommended files were extended and many new were added. On the other hand, a number of so called 'other' files from RIPL-1 are not included in RIPL-2. Testing of these files was not at the level typical for the RIPL-2 files but they may still be a valuable source of additional information. Therefore, RIPL-1 remains available although use of the RIPL-2 data is generally recommended.

RIPL-2 data are organized into segments, which can be accessed through the Contents of RIPL-2 or through the navigation bar on the left. The (ftp) links next to segment names provide direct (ftp-like) access to the RIPL-2 directories. Entire segments (tarred and gzipped) can be downloaded by clicking on a file with a proper segment name and .tgz extension (e.g., masses.tgz). These files are placed in their respective RIPL-2 directories.
