α-d capture with formation of ⁶Li and the isoscalar E1 multipole

We present results of a calculation of the low-energy fusion reaction α+d→⁶Li+γ. In this calculation ⁶Li was treated as a three body α-2N system in the framework of the multicluster dynamic model with Pauli projection (MDMP). To construct the ⁶Li wave function with a high precision a large basis is used for the radial wave function of α-2N relative motion in the ground state of ⁶Li. We pay special attention to the asymptotic region of this radial function. We obtained good agreement with experimental data on both angular distribution and total cross section by taking into account the contribution of the isoscalar E1 multipole.
