Consistent Description of the ~(12)C(0_2~+) State

摘要

The excited 0_2~+ state of ~(12)C is of key importance for description of the triple-a reaction, which is the only way for helium burning in stars. Authors' efforts to calculate the lowest 0~+ states within the framework of the rnα-cluster model are summarized and discussed. In particular, the recently calculated 0_2~+ state's width and 0_2~+ → 0_1~+ transition density are in good agreement with the experimental data.
