摘要：We use the public available TALYS code to study the spectral and temporal evolution of nuclear reactions in low-density astrophysical plasmas with ion temperatures T 1010 K. Such studies are of great interest in the context of scientific programs of future low-energy cosmic gamma-ray spectrometry. The reaction rates logarithm have been fitted as a polynomial function of temperature with seven free parameters. This makes this network convenient for calculations of reactions, especially in the case of time-dependent plasma temperature. We study the chemical abundance and gamma-ray lines emissivity evolution, and present some preliminary results for light elements such are D, T, 3He, 4He, 6Li, 7Li, 9Be, 10Be.
