    Astrophysical S-factor of the N-12(p,gamma)O-13 reaction in relation to Population III star evolution

  • Original language description

    The reaction cross section for the direct radiative proton capture on the the drip line nucleus N-12 - N-12(p,gamma)O-13 - was studied at the Cyclotron Institute/Texas A&M University using the indirect asymptotic normalization coefficient method. This reaction is important in the hot pp chain nuclear burning processes in hydrogen-rich massive objects (Population III stars). The astrophysical S-factor of the direct proton capture was determined at zero energy yielding a value of S-1-12(DC) = 0.31(5) keVb. Interference between direct and resonant capture leads to a further enhancement of a factor of two.

  • Czech description

    Účinný průřez přímého radiačního záchytu protonu na jádru N-12, N-12(p,gamma)O-13, byl studován na cyklotronu Texasské A&M Univerzity pomocí nepřímé metody asymptotických normalizačních koeficientů. Tato reakce je důležitá v jaderných procesech pp řetězuv masivních objektech bohatých na vodík(hvězdy populace III).
