Nuclear reactions govern major aspects of the chemical evolution of galaxies
and stars. Analytic study of the reaction rates and reaction probability
integrals is attempted here. Exact expressions for the reaction rates and
reaction probability integrals for nuclear reactions in the cases of
nonresonant, modified nonresonant, screened nonresonant and resonant cases are
given. These are expressed in terms of H-functions, G-functions and in
computable series forms. Computational aspects are also discussed.
