  A brief survey of nuclide abundances in the solar-system and in cosmic rays
and of the believed mechanisms of their synthesis is given. The role of
spallation processes in nucleosynthesis is discussed. A short review of recent
measurements, compilations, calculations, and evaluations of spallation cross
sections relevant to nuclear astrophysics is given as well. It is shown that in
some past astrophysical simulations, old experimental nuclear data and
theoretical cross sections that are in poor agreement with recent measurements
and calculations were used. New astrophysical simulations using recently
measured and reliably calculated nuclear cross sections, further researches in
obtaining better cross sections, and production of evaluated spallation cross
sections libraries for astrophysics are suggested.
