摘要：

The Coulomb dissociation reaction Pb-208(O-14, N-13 p)Pb-208 was measured at E(in) = 87.5 MeV/u to determine the radiative width GAMMA-gamma of the 1- state in O-14 at E(ex) = 5.17 MeV. This state dominates the radiative capture process N-13(p, gamma)O-14, a key reaction in the hot CNO cycle of hydrogen burning in stars. We have deduced GAMMA-gamma = 3.1 +/- 0.6 eV with the help of a coupled channel calculation. The validity of the technique was confirmed in the case of the Pb-208(N-13, C-12 p)Pb-208 reaction exciting the 1/2+ state in N-13 whose width is known.
