Benchmarking ten codes against the recent GSI measurements of the nuclide yields from [sup 208]Pb, [sup 197]Au, and [sup 238]U + p reactions at 1 GeV/nucleon
A qualitative and quantitative comparison of the recent GSI measurements of the nuclide yields from {sup 208}Pb and {sup 238}U at 1 GeV/nucleon and {sup 198}Au at 800 MeV/nucleon interactions with protons with the codes LAHET (with both ISABEL and Bertini options), CEM95, CEM97, CEM2k, CASCADE, CASCADE/INPE, YIELDX, HETC, and INUCL is presented. The predictive power of these codes is reasonable for nuclides in the near spallation region but is worse for deep spallation and much worse in the fission region. None of these codes agree well with the data in the whole mass region of product nuclides and all must be improved to become reliable tools for accelerator-driven applications

MCNP(TM) Version 5.
The Monte Carlo transport workhorse, MCNP, is undergoing a massive renovation at Los Alamos National Laboratory (LANL) in support of the Eolus Project of the Advanced Simulation and Computing (ASCI) Program. MCNP Version 5 (V5) (expected to be released to RSICC in Spring, 2002) will consist of a major restructuring from FORTRAN-77 (with extensions) to ANSI-standard FORTRAN-90 with support for all of the features available in the present release (MCNP-4C2/4C3). To most users, the look-and-feel of MCNP will not change much except for the improvements (improved graphics, easier installation, better online documentation). For example, even with the major format change, full support for incremental patching will still be provided. In addition to the language and style updates, MCNP V5 will have various new user features. These include improved photon physics, neutral particle radiography, enhancements and additions to variance reduction methods, new source options, and improved parallelism support (PVM, MPI, OpenMP)

Experimental and theoretical study of the residual product nuclide yields in thin targets irradiated with 100-2600 MeV protons.
The work is aimed at measurements and computer simulations of independent and cumulative yields of residual product nuclei in thin targets relevant as target materials and structure materials for hybrid accelerator-driven systems coupled to high-energy proton accelerators

Product formation in proton-induced reaction in the radioactive [sub 129]I target at E[sub p]=660 MeV (a comparison with model calculations).
Isotopically enriched {sup 129}I targets (85% {sup 129}I and 15% {sup 127}I) were exposed to a beam of 660-MeV protons at the JINR DLNP Phasotron and a total of 75 residual products were obtained
