Scattering from 12 to 17 MeV

Coulomb force effects in low-energy α-deuteron scattering

“…torily, whereas the potential αN -II that avoids the Pauli forbidden state in S-wave by the local repulsion clearly fails in accounting for the scattering data, especially at E d = 17 MeV, although the 6 Li bound state properties predicted by both potentials are very similar. The potential αN -III also fails in accounting for the experimental data at E d = 4.81 MeV, but the difference between predictions using αN -I and αN -III is found to be mostly due to the differences in P -waves.…”

“…Another important consequence of this work is that it allows to ascertain with greater confidence the quality of the αN force models one uses to describe αd observables as well as structure and reactions of 6 Li and 6 He. Although at present there are too large uncertainties in the parametrization of P -and D-wave interactions that need to be improved, this work clearly indicates the superiority of the attractive S-wave potentials supporting a Pauli-forbidden state (that is projected out or moved to a large positive energy) over the repulsive S-wave potentials.…”

“…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 ).…”

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].…”
