Warm CNO nucleosynthesis as a possible enrichment mechanism for oxygen and fluorine isotopes

New rates for proton capture reactions on the radioactive nuclei /sup 17/F and /sup 18/F were calculated and compared with previous ones. The influence of these new rates as well as new experimentally determined rates for proton capture on /sup 18/O on isotopic abundances in mass range A = 17--19 ar...

Zusammenfassung:	New rates for proton capture reactions on the radioactive nuclei /sup 17/F and /sup 18/F were calculated and compared with previous ones. The influence of these new rates as well as new experimentally determined rates for proton capture on /sup 18/O on isotopic abundances in mass range A = 17--19 are discussed in terms of reaction-network calculations.
