Three-body calculations of triple-alpha reaction

Ishikawa, S.

Understand

Recently, the triple-\alpha (3\alpha) process, by which three 4He nuclei are fused into a 12C nucleus in stars, was studied by different methods in solving the quantum mechanical three-body problem.

  • Their results of the thermonuclear reaction rate for the process differ by several orders at low stellar temperatures of 10^7 - 10^8 K.
  • In this paper, we will present calculations of the 3\alpha process by a modified Faddeev three-body formalism in which the long-range effects of Coulomb interactions are accommodated.
  • The reaction rate of the process is calculated via an inverse process, three-alpha (3-\alpha) photodisintegration of a 12C nucleus.
