In: Proceedings of the 10th Yukawa International Seminar: YKIS01: Physics of Unstable Nuclei, 10., 2002, Kyoto. Anais… Kyoto: progress theoretical physics publication office, 2001. v. 146. p.634-635.

Acesso em: 27 set. 2012.http://www.repositorio.ufop.br/handle/123456789/1450We derived analytic formulas of the effective astrophysical S factor, Seff, for a non- resonant reaction of charged particles using a Taylor expansion of the astrophysical S factor, S(E), and a uniform approximation. The formulas will be able to generate more accurate approximations to Seff than previous ones.en-USTrabalho apresentado em evento
