Astrophysical $S$ -factor of the direct $α (d, γ)^{6}$ Li capture reaction in a three-body model

E.M. Tursunov · Daniel Baye · S.A. Turakulov

At the long-wavelength approximation, electric dipole transitions are forbidden between isospin-zero states. In an $α + n + p$ model with $T = 1$ contributions, the $α (d, γ)^{6}$ Li astrophysical $S$ -factor is in agreement with the experimental data of the LUNA collaboration, without adjustable parameter. The exact-masses prescription used to avoid the disappearance of $E 1$ transitions in potential models is not founded at the microscopic level.
