Here, data from a Coulomb dissociation experiment on N-20,N-21 are reported. Relativistic N-20,N-21 ions impinged on a lead target and the Coulomb dissociation cross section was determined in a kinematically complete experiment. Using the detailed balance theorem, the N-19(n,gamma)N-20 and N-20(n,gamma)N-21 excitation functions and thermonuclear reaction rates have been determined. The N-19(n,gamma)N-20 rate is up to a factor of 5 higher at T < 1 GK with respect to previous theoretical calculations, leading to a 10% decrease in the predicted fluorine abundance.<br />Ministerio de Economía y Competitividad (MINECO)<br />GSI (FE, DR-ZUBE)<br />Bundesministerium fur Bildung und Forschung (BMBF)<br />Helmholtz Association Detector Technology and Systems Platform<br />Hemholtz Association Germany through Nuclear Astrophysics Virtual Institute (NAVI)<br />Swedish Research Council<br />HIC for FAIR<br />TU Darmstadt-GSI<br />Portuguese FCT project<br />UK STFC<br />US NSF<br />US DOE<br />Depto. de Estructura de la Materia, Física Térmica y Electrónica<br />Fac. de Ciencias Físicas<br />TRUE<br />pub
