Coulomb force effects in low-energy α-deuteron scattering

“…The definition of the arclength S along the kinematical curve is the standard one as in Refs. [8,9,10]. Even when the Coulomb effect is large the convergence is impressively fast, e.g., the screening radius R = 10 fm is practically sufficient for the elastic αd scattering at 4.81 MeV deuteron lab energy in Fig.…”

“…The αd scattering has been studied extensively in the past, both experimentally and theoretically [5,6,7,8,9,10,11,12]. Although αd is a six-nucleon system, at low energies, to a good approximation, the α particle may be considered a spin zero structureless boson, and thereby the theoretical description of αd scattering may be reduced to a three-body problem made up of one α and two nucleons (N ).…”

“…Results obtained using the potential αN -I with (without) Coulomb are shown as solid (dashed) curves. The experimental data are from Ref [9]…”

Low-energy deuteron–alpha elastic scattering in cluster effective field theory

“…The analysis of d−α elastic scattering data, to obtain the correct energy dependent phase shifts of this process and determine the corresponding level parameters of the 6 Li nucleus, has been studied widely in the past decades. The d − α scattering has been studied extensively in the past [1][2][3][4][5][6][7][8][9][10][11], and the low-lying levels of 6 Li have been extensively investigated both experimentally and theoretically [12][13][14][15][16][17]. Recently, the d − α scattering was investigated using the screening and renormalization approach in the framework of momentum space three-particle equations [18].…”
