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