Microscopic study of the triple-α reaction

We present a microscopic dynamical study of the reactions involving three 4He clusters. We show that the much discussed triple-α linear chain configuration of 12C is formed with a certain lifetime and subsequently makes a transition to a triangular configuration of 12C and then to a configuration ne...

Description
Summary:We present a microscopic dynamical study of the reactions involving three 4He clusters. We show that the much discussed triple-α linear chain configuration of 12C is formed with a certain lifetime and subsequently makes a transition to a triangular configuration of 12C and then to a configuration near the ground state. Time-dependent Hartree-Fock theory coupled with a density constraint is used to study the properties of these configurations.
