Abstract
At the long-wavelength approximation, electric dipole transitions are forbidden between isospin-zero states. In an \(\alpha +n+p\) model with \(T = 1\) contributions, the \(\alpha (d,\gamma )^6\)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 E1 transitions in potential models is not founded at the microscopic level.
