Exchange mechanism of dα interaction and vertex constants of 6Li

In this work, we use a model for describing the dα interaction in a 6Li nucleus, in which the dα nuclear potential is written as the sum of the local folding potential and a nonlocal term originating from the deuteron exchange mechanism and corresponding to a three-deuteron component of the 6Li wave function. This model was used to calculate the nuclear vertex constants and the corresponding asymptotic normalization coefficients of 6Li in the dα channel. Both values L = 0 and L = 2 of relative dα orbital angular momentum L were considered. Calculations were performed with and without allowance for the Coulomb dα interaction.
