摘要

We present Skyrme-force Hartree-Fock calculations of metastable three-alpha chain-state configurations in C-12, C-16, and C-20. A microscopic dynamical study of reactions involving three He-4 clusters shows that the triple-alpha linear chain configuration of C-12 is formed with a certain lifetime and subsequently decays into a triangular configuration of C-12 and then to a configuration near the ground state.
