Abstract
In the recent work at Notre Dame, correlations between three carbon isotope fusion systems have been studied and it is found that the fusion cross sections of 12C+13C and 13C+13C provide an upper limit on the fusion cross section of the astrophysically important 12C+12C reaction. The aim of this work is to continue such research by measuring the fusion cross section of the 12C+13C reaction to lower energies. In this experiment, the off-line activity measurement was performed in the ultra-low background laboratory and the fusion cross section for 12C+13C has been determined in the energy range of Ecm.=2.5-6.8 MeV. Comparison between this work and several models is also presented. [ABSTRACT FROM AUTHOR]
