Three-Body Calculation of ⁴He(αα,γ)¹²C Reaction at Stellar Energies

The triple-alpha reaction is the key to our understanding about the nucleosynthesis and the observed abundance of ¹²C in stars. On the basis of our model, the triple-alpha radiative capture process is studied by using the three-body Faddeev approach as well as two- and three-body electromagnetic currents. The bound and resonance states of ¹²C are calculated via an inverse process: three-α photodisintegration of a ¹²C nucleus.
