Resumo: | The first excited Jπ= 0 + state of 12C, the so-called Hoyle state, plays an essential role in a triple-α (4He) reaction, which is a main contributor to the synthesis of 12C in a burning star. We investigate the Coulomb screening effects on the energy shift of the Hoyle state in a thermal plasma environment using precise three-α model calculations. The Coulomb screening effect between α clusters is taken into account within the Debye-Hückel approximation. To generalize our study, we utilize two standard α-cluster models, which treat the Pauli principle between the α particles differently. We find that the energy shift does not depend on these models and follows a simple estimation in the zero-size limit of the Hoyle state when the Coulomb screening length is as large as a value typical of such a plasma consisting of electrons and α particles. |

The first excited Jπ= 0 + state of 12C, the so-called Hoyle state, plays an essential role in a triple-α (4He) reaction, which is a main contributor to the synthesis of 12C in a burning star. We investigate the Coulomb screening effects on the energy shift of the Hoyle state in a thermal plasma environment using precise three-α model calculations. The Coulomb screening effect between α clusters is taken into account within the Debye-Hückel approximation. To generalize our study, we utilize two standard α-cluster models, which treat the Pauli principle between the α particles differently. We find that the energy shift does not depend on these models and follows a simple estimation in the zero-size limit of the Hoyle state when the Coulomb screening length is as large as a value typical of such a plasma consisting of electrons and α particles. |
