摘要：
The N-15(p,gamma)O-16 reaction links the CN cycle to the NO cycle allowing for the production of the oxygen and fluorine isotopes during the hydrogen burning in novae and AGB stars. This reaction has been intensively studied by the LUNA collaboration. In this contribution the experiment performed using a BGO detector and a windowless gas target setup is described. The measurement of the astrophysical S-factor has been done in the center of mass energy range from 90 keV to 230 keV. The cross section is found to be a factor two lower than previously believed.
