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+¹³Cand 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 ¹²C+¹³C and the fusion cross section for has been determined in the energy range of E_c.m. =2.5–6.8 MeV. Comparison between this work and several models is also presented.
