The RIPL-2 library is close to completion, with public release expected in July 2002. Users of reaction codes will benefit considerably from the gener­ation of a complete and consistent set of starting parameters to give sensible results for cross sections and spectra. However, RIPL-2 should be further ex­tended and continuously updated in order to retain the relevance and value of the library to the users. At the recent co-ordination meeting in Vienna, December 2001, the CRP participants discussed possible improvements of the current project and formulated recommendations for further activities. These finding are summarized below:

• RIPL-2 provides valid sets of parameters for spherical and near-spherical nuclei. On the other hand, data for the deformed nuclei are scarce and less accurate. In particular there is a need for more Coupled-Channels potentials and 7-ray strength functions for the deformed nuclei.

• Special techniques should be applied for the determination of parame­ters for nuclei far from the stability line for which there are usually no experimental data available. These nuclei are important for ADS and astrophysics.

• New experimental data from the recently initiated projects (HINDAS and N-TOF at CERN) should become available within a year or two, offering possibilities for testing RIPL-2 parameters. The same is true for the SNS facility at Oak Ridge at a somewhat longer time scale.

• RIPL-2 library should be complemented with a set of routines for the calculation of certain input parameters (such as level densities, binding energies, 7-strength functions, etc.) in order to facilitate user access to the database and to avoid misuse of the parameters.

• More attention should be dedicated to the use of microscopic models for producing parameters. Parameters related to the fission channel contained in RIPL-2 need more accurate analysis and improvement.

• The problem of collective enhancement of level densities should be addressed in more detail in order to provide a reliable prescription for calculating level densities in deformed nuclei. The latter are often needed for ADS and new reactor concepts. [3]

• Use of the results obtained in heavy ion induced reactions could be helpful in determining model parameters, especially for nuclei far from the stability line.

• Medical applications require charged particle reactions, which could be better represented in the parameter library.
