摘要：
The nucleus 11C plays an important role in the boron-proton fusion reactor environment as a catalyzer of the 10B(p, alpha)7Be reaction which, by producing a long-lived isotope of 7Be, poisons the aneutronic fusion process 11B(p, 2 alpha)4He. The low-energy cross section of 10B(p, alpha)7Be depends on the near-threshold states 7/2+1 , 5/2+2 , 5/2+3 in 11C whose properties are primarily known from the indirect measurements. In this work, we present the theoretical analysis of these resonances and their collectivization via the coupling to the proton emission threshold. By using the shell model embedded in the continuum, we show that a significant collectivization takes place that enhances the spectroscopic factor of proton capture confirming the phenomenological value of Wiescher et al. [Phys. Rev. C 95, 044617 (2017)].
